I don't know what that spells

The other day I read a post from my sister in-law, Angie. You can read it by clicking here. She was talking about Morgan trying to spell. I thought of that yesterday when Isabella, Zach and I were at Dunkin Donuts. When we were done, she took the trash over to the trash can and put the stuff in. She then looked at the door on the trash can that said "THANK YOU." She put her finger on each letter, and said "T-U-V-W-X A-B-C" she then ran over to me and said, "I don't know what that spells!" I, and the other folks eating donuts, had to laugh.
