Gentlemen
have a set of rules. Or a specific set of codes that differ from the "average" man.
Gentlemen have things that only a gentlemen do.
According to urban dictionary (I know, I actually searched for it. <_<), Urban Dictionary: Gentlemen
Hence, there are things that a gentlemen does and things that they do not do.
I once heard someone say that "Pool" (billard, that sort of thing) is a gentlemen's game. I agree. Only in the old contexts, of course.
Still, if pool is a gentlemen's game, I have to say that "Boxing" is a gentlemen's sport.
A boxer is someone that is calm (in a sense), have a type of "aura", able to plan quick strategies and think for himself, someone that fights according to his rules/philosophies and someone who trains himself.
No matter how I look at it, a real boxer is a gentleman.
Look at this guy:

A GENTLEMAN.
It's true.
If you're having doubts if you are a real gentleman, just ask yourself one thing. Do you have a moustache like Mr. Dudley (the picture) does? If yes, chances are you are a real gentleman.
Later...
P.S. Why does everyone seem to be so pressurized by the exams? Should I be panicking too?
