We go to Vegas annually to visit BF's dad. One visit, we were at dad's friend's house, and the friend's son had some guests too. I kept looking at one of them who looked real familiar, and we realized that we used to hang out in a group (we had a common friend) when he was living in Hawaii.
A small world in another sense...I worked for a small gift shop years ago, and after working there a couple years, my boss's wife figured out that we were actually related!! Another thing about this shop...while I was in high school, I was infatuated with baseball players and would read the sports page religiously. I saw a picture of a guy I thought was cute (I actually cut it out and saved it). Fast forward to my interview with the shop owners...boss's wife tells me about this great guy that works for them at their other shop...it's the baseball player I was infatuated with from high school! I went over to the other shop and introduced myself and we bacame very good friends (nothing more though!).
