the answer to whatever you lean out of your window to ask me is almost invariably 'NO'.
On the off chance that your question is "Would you like me to go away and stop following you like a creep in my giant black truck?" then the answer is yes. This is probably the only time the answer will be yes.
Seriously. Has this tactic ever worked for you? In what appears to be 40 to 50 years of existence, has one girl ever said "yes, I think I actually would like to get into the truck of a stranger"?
