Positive Teenagers

Today, as with a very few other days, I actually talked to my teenagers on the phone after school, discussed their days and did NOT end up in a fight, with at least one of them. I cherish these times but would like to have them happen more.  I do really have good kids overall but they are still teenagers and are living up to the stereotypes to the fullest. They can sometimes be very difficult to handle. Always looking for suggestions.
