I personally think the number 137 appears everywhere. Omg it's in my post too! D:
I'm allways seeing the number 123 and 117.
To be honest, if you look around, lots of number repeat a heck of a lot around you. It's only the numbers that tend to mean something to you, that stickoutand seem odd.
123 and 117 stick out for me because; 123 is the result I got on an unofficial IQ test, which i thought was cool, seeing it's that each of the numbers in it are, well, Consecutive. 117 sticks out, because I used to be a rather big Halo Fan, and for those who don't know, 117 is the [ID No?] of the "Master Chief"....Sad isn't it? :(
