My wife gave my a good laugh the other day. I giggled when she was crying over spilled milk
Laughing at your wife is kinda rude. Did that make you feel good?
I felt very proud of my achievement at that point. A colleague later told me it was mean to laugh at her like that.
Your colleague is probably right. I don't know the exact context, but you're upsetting your wife instead of supporting her.
Shut up. She deserved it. I bet she would laugh too if it happened to me.
Instead of laughing when your wife has problems try consoling her. Wouldn't you rather she feel like you have her back than to feel ridiculed?
