You're in this woman's home even if it's to pick up your child. Even if you only wave it's only being polite. When your child grows up you will understand but in the mean time say "hi" it doesn't take much effort.

Say, "Hey there.  How you doing?" <Wink>\n"I know you have been checking you out as often as you have at me."

If someone asks you if you need help, move head up and down. If someone asks you if you are alright, shake head from side to side.

Like when people say "what's up?" What do they think is up?

Touching one's face.\nConstant blinking.\nLooking down.  Looking up means answer unknown.\nP+ssing one's pants is a dead giveaway *L*

It depends on who is staring.  Some people just do that and it doesn't mean anything.  Without having a mind reading device it's impossible to know.

"Hi" works.\n\nI wouldn't recommend tapping her on the shoulder, though.
