Well, they distinguish various personalities in me. At the moment they see me as:

a) emo - "because I don't talk too much and listen to music.";
b)psycho - after mentioning a certain accident with my appearance at least two people were staring at me all week;
c) fuckin' Pokemon - I've no bloody idea, what was that about; -.-"
d) satanist - the same as above;
e) Robin Hood or Monk - caused by my habit of wearing hoods; ;]

Probably within next two years I'll have some more random nicknames but the funny thing is: they can't see The Mark.* ;]

* - which is a joke. ;D
