This one came in by PM:
"When I rub my wife's feet, her response is "okay, what did you do wrong?" or "I know what you want".
Now of course, we all know that I want the goods, but I don't want it to look like those are my intentions. I'm okay rubbing her feet a few times during movies nights and falling asleep when my head hits the pillow. I figure that I'm building up credit. The question is, how long are those credits good for? Just curious.
Curious from Colorado."
What is the square root of -1? It is the impossible, unsolvable puzzle. There is no answer to your question.
Basically, foot rubbing is an acceptable way of proposing some love. It's much better than sending her a text that says, "Wanna &*#%?"
