Munchkin has no scruples about using his charm to get what he wants. He's gotten sets of rubber gloves from every medical practitioner he's ever seen, and half of the firemen in our town. He'd have quite the collection by now, but I toss them out after he's shredded them by stretching the gloves over his shoes.
The other night, we went with our realtor to look at a house and the owners had placed a basket full of those little blue footy things for people to wear on their shoes. Munchkin took off his shoes, and then insisted on wearing the footies because he said his socks were dirty. I was just waiting for him to ask to keep a set.
Munchkin waited until we were all the way out of the house and the realtor had locked the door before he said, "They have a lot of footies... I think they have too many footies." Guess who schmoozed his own pair.
