Boys are set to not allow anyone to add friends, and after a while, they are set to allow anyone to add friends without verification. Why?
Maybe boys are sometimes in a bad mood or want to be quiet, so they temporarily turn off the function of adding friends. Maybe after a while, I am in a good mood, or I have been able to sort out my feelings. So I resumed making friends. Maybe that's the mood. Much more lively, want to be quiet. When I am quiet, I want to be lively again.
