being the one to initiate contact & plans is often the key to make friends. I used to catch up with older friends from middle school, hobby course etc on facebook and plan a date & get closer again. Often it's also easy to be friends with their friends when party/girls night is planned ahead.
Learned the older you get it's not necessary hard making friends, it's just being the one to initiate conversation & meetings and keep in touch.
