As far as relationship blunders go, arranging your mother and family to be at your wedding anniversary behind your wife's back sounds like a big one. Not sure what was going through the guy's mind when he decided to covertly get his mom into the mix, but the wife is understandably peeved. For another interesting one, here's a girlfriend who beat her upset boyfriend at a steak eating challenge.
It's an actual case of "I'm not a doctor, I just play one on TV." Some folks are so far in that they can't really be helped. It's a regrettable part of life that there are people walking around like this. For example, take these wildly dumb things people have heard or these facepalm moments.
This guy asked folks on Reddit whether or not he was in the wrong for stranding his roommate with full rent, because he simply couldn't take any more of his roommate's strange rules.

Said girlfriend seems to have suffered some kind of trauma in the past, and can't stand being caught alone with the guy when her boyfriend isn't around. Considering the uniquely tough time that we're all living through, and how many folks are forced to be at home most of the time, this created quite the conundrum. So, most folks agreed the guy really didn't do anything wrong.

For those of you who like toilet stories and completely lack class, here's a hilarious airplane bathroom story.
