How many coincidents are there in life?

Have you ever experienced a coincident event with a person? Have you ever experienced a series of coincident events with a person? And I don't mean the man made coincident like the one in the Cornetto advertisement. After 20 years, and now I know someone was so near to me since I was born. We were born in the same hospital, we went to the same kindergarten studied in the same class, we went to the same tuition class and sat to each other just a few rows away, we live in the same housing area, been to the same school, ride on same buses, we spend hours chatting through MSN and now studying in the same area, almost the same field and we are in love. Trust me, there are more. Weird enough, it took us twenty years to turn our heads and look back and see each other, a person who passed by many many times in front of you but you have never spoken a word to. Same fate huh. Even we can't believe it's true. No metter who's playing the trick here, we are not planning to waste this chance again. (we think something happened in our past life =P)
