13

I used to not mind this number and even laugh at it for its many superstitions of extreme kind. Most people believe that it's unlucky that even buildings don't have 13th floor (tell me is you know a building with 13th floor, i'll really go to that place to check it out). Chinese on the other hand say that it is actually a lucky number (i don't know why though).

But now for me, 13 is a special number.
