Hi,
Don't be too upset about it. Dirty old men that bio za bor cleavage
are dime a dozen. Since you are short, just take note of the place
you are standing at on the mrt lor, or you can tactically place
your hand to cover up lor. Some hum sup men buey paiseh one, you
can stare back at them and they still die die want to continue to
bio with jaw apart. Coz bioing does not break any law so no case
against them. Your best bet is to protect yourself and ignore them
