[boring-story]
One day I was feeling down so I temporarily changed my nickname on IRC to
LifeSucks (I've had lots of strange nicknames changing every few weeks before that). After a day or so I decided to change it to
Sucks for some reason.
Then it soon became
Socks.
I think I sticked with that for a few weeks, and tried
Sox too, but I was annoyed by the fact "Socks's" and "Sox's" look so ugly, so I finally changed it to
Sock. Some time later, I tried the lowercase
sock and I liked it, and I just never changed it again. I've probably had it for over 5 years now.
A few months ago I decided to change it again, but nobody wanted me to because they've all become accustomed to it, so I finally just dropped the idea. Although, I started using my real name as my username in some places instead of "sock".

There is, however, some dark hidden psychological reason for me sticking to that nickname, I believe. But that is for me to know and for you to wonder.
