A chat on subreddit /r/NoStupidQuestions

I've definitely had conversations with older colleagues that have adult children around my age (late 20s to early 30s) that led to me having to say "please, stop talking to me like I am your kid."

On a funnier note, when I was in graduate school (mid-20s), I was paying for a hair cut and the person checking me out asked what grade I was in. That made me go 😐😐😐.

I started answering that one with "Me? I'm in the 20th grade."
