How often do you talk to your friends?

I was just wondering how often you talked to your friends over the summer. Also, how often do you talk to them during the school year? For me, I talk to my best friends about once or twice a month in the summer and we hang out a few times and during the school year I talk to them several times a week even though we aren't in the same school. With my other friends, I have MAYBE one brief, casual conversation with each of them over the summer and during the school year, even though we are in the same school, I only talk to them two or three times a week. What about you guys?
