Grammie, I need money

Mackenzie never has no likely ever will be known as subtle. While shopping yesterday for Angel tree gifts, Santa was spotting in his large chair, waving at girls and boys. Mackenzie started walking right up the red carpet until I stopped her and said we should ask Grammie if we could borrow some money because I didn't have any cash. Taylor hung back a bit not sure what to do. While I was telling her of our cash dilemma, Santa picked out two reindeer antler hats and candy canes and waved her forward. Taylor didn't hesitate then and went up to Santa, excited at his gifts. Mackenzie then returned with a twenty dollar bill, gave the money to me and went up to see Santa and what Taylor had. Santa put together the hats for the girls and was fitting them on when the photographer asked him to wait as we'd like to get a photo. I had been chatting with the photographer. The girls sat pleased as punch, for the first time ever, on Santa's knee. As there was no line up they had quite a chat as well. Taylor keeps reminding Mackenzie that she told Santa that she would be good until Christmas eve. Taylor also adds that she told Santa that she would try her best because we all make mistakes sometimes. - Grammie appeared later and explained that Mackenzie had found her in the Dollarstore, came right up and abruptly said, "Grammie, we need money." I don't think I've ever not been afraid of Santa, a stranger in a stranger beard. I also don't think I've ever been that bold asking for money. Who is Mackenzie related to anyway?
