Numb3r

My favourite numer is 4.
I think that it is my lucky number because:
-I was born on April
-I started do date my first girlfriend on 4th May
-At school I used to the number 4 for 4 years
-I am the older brother, with 4 years of difference
and have other reasons that I don't remember now.
Every time that someone sais "Say a number" I say 4. I don't know very well why, but 4 is my favourite.
