OK. You saw...

Yes indeed. But if she frowns instead of smiling, then one will not even ask for coffee anyway!

What if she miles as a good gesture only...Not every 'smile' is welcoming you know. Just a thought.

I think there was a skit at SNL a while ago, where this man goes to a girl and said:

Something like that:

You are so good looking, can we get together. I spend some money on you and then we go to my place and do the "deed"?
He got slapped, and she said "you pervert! Who do you think I am?"

Next Skit: Same man goes to her, asked her the name, then said how about we go to a nice dinner, we talk, then a movie, then we go to my place, and watch something on TV then we do the "deed"...

She said "that's so wonderful and romantic"
