MY COMMENTS:

As for the girl who gave you the "message service", you
need to interpret that as follows:

She didn't find you interesting enough to give you her
REAL number. That's OK, you're doing a great job... but
you need to get EMAILS and REAL NUMBERS in the future.

One thing you can do is say "Is this a phone that you
actually answer in person?" If not, then give it back
to her and say "It's OK, give me your number."

When a woman asks your age, just say "Old enough to
know better than answer a question like that one...
how old are YOU?"

If they insist, just add 20 to your age and tell them
that. Be serious about it and really bust their balls.

Keep it up, you're probably close to a breakthrough!
