I Can Be More Stubborn Than You Can

My granddaughter came to visit me for lunch the other day along with grandpa. My principal had a cute little purse to give her, filled with some goodies. But the granddaughter is so stubborn, she wouldn't say thank you. We coaxed and tried many times. So, grandpa made her give it back. Didn't upset her at all. As they left the building, grandpa overheard her comment, "I'll get it later."
