Yes - I have many acquaintances, but during most periods of my life, only one or two people I considered “friends”. Probably because I tend to apply that label very conservatively, based on my own level of commitment to that person.
I think there are many different ways how people “practice” their friendships, some ways will allow to cast the circle wider (so they think of themselves of having many friends, by their standards), other ways will cast the net very tightly.
Quite possibly, people consider someone “a friend” from their perspective, while the other person thinks of them more as close, long-time acquaintances.
@_moneywoise: It is possible that “the” friend is just waiting to be found at some college - but you can’t know which one - it might even be someone you haven’t run into yet at your current school. Transferring doesn’t seem like a wise approach - your odds at a better social outcome are 50/50 at best.
