Have the guy meet the parents yet?
actually, 21 years old is not that old afterall.....because being a
gal, the parents are naturally more concerned for her.
However, i think she has to gain more trust from her parents b4
they will lift the curfew.
sometimes, curfew are broke in a gradual way. If the timing is
10pm, once a while, call home earlier, says 8pm, and tell them you
will be home around 1030 or 11pm, saying that you are with a gp of
friends..however, dun mis use this method too often.
slowly, 11 to 12pm..however, from my gal friends' experience, this
transition takes ages..so just bear with it lor
Most imptly, the parents must know she is going out with friends or
bf who are trustworthy. So, its good for the bf to know the parents
first, b4 attempting to stay out late with him..
Next time as a mother, will you want your daughther to stay out
late with a bf whom you never met b4? or will you be more flexible
if she is with some1 u have seen and know?
