<kalista! great seeing you girl - miss you>
I think what Liza meant by friction is sexual tension - you flirt and be coy - build it up until it erupts.....you are a natural flirt Kalista so Im sure you know what Im talking about
You both barter at each other and challenging each other gently - not in rough way but in a way that increases tension
I love friction because it makes it all exciting - if someone reveals himself too much and too early to me, I lose interest.
But then again everyone interprets friction differently...................
