Birthday in Belgium

I just booked a ticket to Belgium this weekend! A friend of mine turns 20 on Sunday and of course I want to be there to celebrate her. We met in Spain a bit more than 1 ½ year ago when we were studying Spanish, and spent two weeks together before she had to go back to Belgium. I'm usually really bad at keeping contact, but as they say, true friendship lasts. It's been a long time since I saw her now, I think it was sometime in the winter. The fact that we live in different countries complicate it a bit, unfortunately. But now I'm finally going there and I can't wait to see her!
