I won’t say whether it’s better or worse to ban phones during break, but I do think it is worthwhile to point out something that you might not know, given that you’re still in school.
School is most likely the last time in your life to have actual, true friends. In college, and especially in work, your friends will almost certainly be fair weather friends, friends made out of convenience rather than anything substantial.
I get that school sucks. I still think so. But there’s some benefits to how schools are run that you won’t recognize until you’re already out of school. Your social life will absolutely get tougher and you’ll be more isolated. So, my advice is to take the bad with the good. Have some fun with your friends in-person, because that’s really never going to happen again. Please don’t waste your school life on your phone.
