I caved and just said sure even though I had made plans as it is my day with the kids. She didn't seem to care at all though.
"How's that workin' out for ya???"
No sh!t, a woman sure finds a little , say yes to everything, will always cave, , man very attractive.
I would never ever let that happen, in fact I would call her right now and say, you know what I am having this thing as I originally planned, you can do what you want on your time with them, but this is my time.
