How can I help my friend who is moving because he is gay?

If he was born there he'll be back, and besides, now you get a free place to stay when you visit Berlin. He is spreading his wings, be free little bird, go explore this great big world. What you can do is to organize a little Good Luck Party before he leaves. Make it a fun and happy time so when he wants to get away he has a place to go. That way everyone has fun. Good idea. Oh, and funny presents. Stupid things giftwrapped are always fun.
