Good times with friends {& a very happy birthday to a beautiful boy}

Yesterday we spent the afternoon and a good part of the evening celebrating the first birthday of Koen, the son of a good friend of mine from high school. A few years ago he moved to Calgary, met the girl who would become his wife, and had his first child. We've seen them a few times since but this was the first time I got to meet his little son.
We had a great time and when the day was over, we said our goodbyes. I don't know when the time will come when I will see them again... Why does the world have to be so big??
