Before:
Gal calls, Guy will pick up or call back within 5-10mins to ask
what happen.
After:
Gal calls,
Guy reject calls, sms to say he is "with customer, having dinner,
with boss etc etc.." or sometimes, totally ignore.
The conclusion is, gals, DUN give guys the chance to get u to be
their gf so easily. Things that are gotten to easily are NEVER
treasured.
