The best birthday present I ever received was a surprise birthday party when I turned 22. I had worked that day, and it was a pretty crummy day. Afterwards a couple of people had agreed to meet up with me for dinner later that night.
Well I was feeling pretty low, and I almost cancelled. But I was so glad I didn't, because when I arrived, all of my co-workers were there. They had brought some decorations and we did karaoke through the night. It was a simple gesture, but one that I still remember and hold fondly. Gifts are nice, but memories like that I cherish far more.
