I have a Russian pen friend whose/who name is Alexei. Swap/swapping e-mails with him is a great fun. It's fun having/have a friend who/shich shares the same interests with you. We both like the same music, sport games and the same subjects at school. I've leant a lot of interesting things about Russia from Alexei. Having/have a pen pal in Russia makes you understand how many things are there to learn/learning.
