I can't believe people still try to pull a stunt like this at weddings and then act all surprised and indignant that someone would tell them it's inappropriate. I mean, what did you THINK was gonna happen? Everyone would just clap and tell you how awesome and bold you are? GTFO!
This maid of honor definitely earned her title by making sure this entitled Karen of a mother-in-law
changed into something more appropriate and didn't try to upstage the bride on her special day. She did wonder if she stepped out of line, but pretty much all of Reddit was unanimous in their approval of her actions.
