I've been thinking about coincidences in my life. There are loads of funny ones, and some that are just plain scary. A lot of my life has been associated to the number 4, 13 and 14. I live in a house whose number is 27 (13 + 14) on road number 4. (I think my address is on whois. Not sure.) When I go to a restaurant where the tables are numbers, there is a 50% chance that if I choose a table, it will be either table 4, 14, or 24 (this is at complete odds with the fact that there are so many other numbered tables).
That meant that when I came to Arrow, I was expecting to stay on the 4th floor, which came true. What I wasn't expecting? Two seniors for actuarial science staying on the same floor (it's one thing to find a senior on your floor, but I think it's another story if you find the president of the Actuarial Students Society on your floor). A person in the room whose door is directly opposite mine - shares a birthday with me. A housemate whose name is highly similar. (if it were the same, I think it would already be safe to say it's time to find out what trick destiny is trying to pull).
Among the funnier ones? HELP University College was founded one day before I was born. My year of birth is 1986. 1+9+8+6 = 24. 2/4 (2nd April) is my birth date. That about all I can think of for now. I don't think it'll be that long before I find more. (Pointless fact: Oh yeah, the Faculty of Economics and Commerce in the University of Melbourne was founded in 1924.) I'd say you can probably find a pattern of some kind in your own lives too if your look hard enough. Funny things happen to a lot of people. :D
