do you believe in penfriend

When i was in the high school,i often wrote to my penfreind to discuss kinds of things.However,we lost each other when i entry the university.Gernerally,it was g great time we had been together.

i ever had a pen friend when i in high school,we communicate everything we know about.but time;s fly,we still dont know each other,the letters are reducing week by week,and until now i even forget that i ever had a pen friend before. i suppose the most factor that cause we lose our contact is that we dont have common interesting,,that;s really sad.except interesting,,what might we talk about?
