Nice to hear so many stories!
I have another friend who is always doing things to make me smile. Yesterday we went to McDonalds for a shamrock shake and we went through the drive through. He told me he wanted to be one of those people who play annoying loud music in the drive through lane. He put on the most annoying thing he could think of and turned up the volume. He didn't even turn it down to get the food! I was dying. You know everyone around us was saying "Jeeze, those people are annoying!".
Another time we found these flyers with fake dollars in them. On one side they looked like real money and the other side had an ad on it. He collected a bunch of them and put them in the center of the atrium where people walk by. We sat there watching everyone walk by as they looked at the money and decided whether or not they should stop to pick it up!
Every once in awhile in these situations I realize that I should never take them for granted, because who knows how long you will know that person or how many more times you will see them. Especially now in my life, since I will be graduating college next year and leaving to start life in the real world. I have no idea what friends I will keep in contact with and which friends I will never see again.
