Someone wished kids upon me after I said I was childfree

I’ve tried to shake this off for days but I can’t so I’m here to rant!

Last week at was chatting with friends from uni when the topic of children came up and I said I wasn’t having any, this one guy who’s known for being a bit… Conservative immediately said «I can already see you with two children by the time we graduate»

WE ARE EIGHTEEN. This guy thought it was appropriate to tell me I was going to have two kids by the time I’m 22, after being told I would be miserable if I had kids.

I told him «why would you wish something like that to happen to me after I said I don’t want kids?» I’m kinda proud of myself for not staying quiet and shutting him up, still mad tho.
