Having a girlfriend = alot of commitment.
I'm 27, no gf, go to work, come home, then go jogging or gym, if
not, play my Playstation 3 or PC online like Final Fantasy
XI.
Worse to worst, i just listen to music, read books, relax.
That's my life lol. 
But some people i know, want a gf very much but when become
attached, they say regret...i wonder how to understand them.
