Last April I ran into a child I used to teach at daycare and his family. He wanted to know where one of the other teachers were, too cute!
In October, I almost ran into the people I used to nanny for. I avoided them like the plague, but I saw them.
This past February we ran into extended family members - initially when my father told my mother he saw them she thought he was crazy. Then we saw them in line for Philharmagic! My father is the president of the LL over here, and he ran into several parents in WDW as well. We were joking with him that he can't go anywhere without being recognized!
When I was a kid, 8th grade, my family went on a trip to Club Med in St. Lucia. It was a business trip for my dad, and luckily we were all able to go. Well, there was another kid from my class there the same week as we were! It was too funny. It truly is a small world.
