Birthday

My best friend here in ITB, Dimas, had his birthday today. He's 19 years old now. I accompanied him for the whole day yesterday. So, where Dimas was, there was me too. We wasted our time yesterday to study and did interesting things.
Today, there's no time to do such things. That's why we did that yesterday. I don't know why, he looked a bit unhappy today. It seems like he doesn't enjoy his birthday. Ya... It may be his first time to celebrate his birthday far from his old friends and his family.
Overall,I've tried hard to make him happy today despite he's really strange today.
