At a party this past Thursday, I met a girl who was born in the same hospital as I was (Danderyds sjukhus), grew up in the town next to mine (Enebyberg), moved to the US in 1995 (same time my family did), went to college in North Carolina, moved to the bay area 3 years ago (ditto). There can't be that many other people out there that have lived closer to me over time.
