Let people know when you have them on speakerphone! Especially when your husband/wife/partner/friend/any other human is within earshot. - u/blueshiftglass

Don't block the footpaths. If you're waiting for something, move off it to the side. We're not obligated to walk around you because you have an ego. - u/God_69_lel

If someone says they’re not drinking tonight, don’t make them feel bad or imply they are being boring - u/slowent

Stand 2m back from the airport baggage carousel. If everyone does it, then enters that ring to grab their luggage and leave, then everyone can see their luggage as it comes and no one is jostling.It never occurred to me until I traveled in South Korea and they had a white line around the carousel that everyone stood on. It was remarkably efficient and I wish the rest of the world adopted it. - u/JoyKil01

If I'm turning away from you I'm trying to walk away, stop continuing to bring up new conversation points. - u/ValStarwind

When someone hands you their phone to use, don't f*cking go through it. It's rude. - u/Sensitive_Suspect_69

People playing music loudly on their phones in public or on public transport especially. No one wants to hear what you're listening to. - u/ajaxx212

Don’t immediately assume it’s okay to smoke in someone’s house, regardless of their living situation. I don’t care if it’s literally a cardboard box or an upscale mansion. Ask first. - u/The-Unseelie-Queen

Stairs are for ascending and descending. Move out of the way when you are done using them. Standing in front of them and looking around like a lost tourist is not one of their functions. - u/FriedBacon90

You don't need to attach yourself to the person in front of you when standing in a queue - u/postmodern-nerd

When someone is helping you move, you offer them pizza and beer, no exceptions. If they don't drink, offer them soda or water - u/On_Too_Much_Adderall

You don't need to be this close when you're talking to me. - u/grantib1

That leaving your shopping cart in the middle of the parking lot is lazy and just plain rude. I hate finding a parking spot only to realize that there’s a f*cking shopping cart already taking up the spot. - u/bananakittymeow

Warn people that you/your kid is sick before turning up at their house/interacting with them. Chickenpox, flu, hand foot and mouth, stomach bug all caught by my toddler in the last 12months and could have been avoided. - u/Medium-Raspberry1122

Respect people's right to say no. It's okay to ask someone for something, or to do something, or whatever - but if they say no, don't pester them or guilt trip them. People who pressure their friends are kind of garbage friends. - u/rgrwilcocanuhearme

Standing in the middle of the supermarket aisle blocking the entire aisle with your trolley while you stare at the shelf is not ok. - u/AlGunner

If someone is hosting you, don’t insult or give a negative critique of their home. Some people have fewer resources than others, only one income to live off of, and have worked very hard to get less, etc. No need to point out home imperfections. - u/paul_rudds_drag_race

Cover your mouth when you sneeze, apparently, people don't know this - u/Ph6r60h

If you’re out at a restaurant/party/event with someone don’t offer any criticisms about their appearance unless they can actually change it. “Oh thank you for pointing out the spot I missed shaving. I’ll just spend the rest of the night thinking about it and how I can do nothing about it.” - u/stupidinanecomments

Don’t ask people to do their job for free, even if you’re friends or family. - u/Inkoko

You only take two slices of pizza max, until everyone has had their fill. - u/Tomatillo_Fluffy

Hold the door open for the person behind you if they are close, at least long enough to prevent the door from being slammed shut on their face. - u/howwouldiknow--

Don’t be talking through movies. I can only say "yeah" and "mhm" so many times - u/oge_mah_ge_kid

If you aren't friends with someone anymore, it doesn't mean you can go around telling their secrets to everyone. "Secrets are secrets and under no condition shall they be broken."It's truly disgusting to see how people don't realize this. It's basic knowledge you should know though it hasn't been made as an actual rule. - u/Kiwi__Offended

If you see me taking off my headphones to listen and answer your question, then immediately put them on again... 5 TIMES... it clearly means that I'm just being polite, not that I'm interested in talking to you, so STOP ASKING ME QUESTIONS. - u/V02D
