I saw a case like this ytd when I went home after work... But
the situation was opposite...
There was this pretty lady on the mrt seat sleeping... She was
aslp then her head tilt to the indian guy on her left... Then the
indian guy wife/gf was standing (dun ask me why she's standing but
the guy is sitting) up, she was glaring then kpkb at the poor
indian guy... His mother/grandmother sitting beside him also
kpkb... 
Then the lady kenna woke up by the noise... so she tried to slp
but fall the other side... There was this young chubby teenage
boy playing some game on his laptop... Then the lady's head
slowly knock into his shoulders... The guy reaction was a
"Tsk"... Then keep trying to siam... like very irritated becoz he
cannot play his game in peace... 
Funny scene~
and
it was a pretty girl wor~ I'm sure some of the guys down here must
be feeling why such things dun happen to them~
I also had to wake a pretty girl up the other time cos her head
was dropping on my shoulder. the head on your shoulder doesn't give
you any advantage or feeling one mah....
