Thx K-Loc.
Well so i accepted the friends request and afterwards wrote her a personal message. Most of the time i had a day delay between replies ( so did she ), is this necessary ? Don't want to look too desperate (not that i'm desperate)
I don't really know what i should do next, reply again sort of playfull, cocky or get more serious and chat about what she does etc. or ask her to go get a drink with me ? It's not that i'm that into her, i see this more as a learning experience and want to do things right.
Is there also any good reading material you could recommend me ? Because most posts in this part of the forum are all about opening etc.
Here' what i said ( i had to translate it so in my mother tongue its probally more funny)
Me : How did the swimming go between all the old, slow people ? If you can call that swimming ofcourse
Pool Girl: Hahaha, yeah after a few lenghts i already got sorrow ( stiff ? ) in my arms:P
I was really shocked to see you again, you have become really muscular.
Me: Ah so that what you call swimming, do a few lenghts, jump in the jacuzzi and check out the guys. Ofcourse i was the only guy worth checking out, unless you like 70 year old men in tight shorts.
Pool Girl: Actually I like them alot

, there were also some little guys of 12 years old but that ain't my thing.
