Apparently pretty small.
I can't get over how frequently it happens! I was keeping track when I first moved here but I lost count. Yesterday while walking to Central Park, my friends happened to be driving right past me on 3rd Avenue (I can't decide what is more bizarre - that I ran into them or that they were driving?). This afternoon I was wandering around near my apartment and ran into a friend I graduated with. These are just two of about 20 random run-ins I've had since I moved here!
I used to get annoyed when Carrie would run into Mr. Big at least once per episode on Sex and the City. Come on, the city is packed full of people - how does she see him that much? Apparently it's not that weird.
Does everyone experience this or do I just have crazy luck?
