Who Ate My Food?

Last night, shortly after dinner, Muddear began calling me. (Mike and I were sitting downstairs, talking and watching television.) As I proceeded upstairs, I saw Muddear in the hallway at the top of the stairs.

"Is everything alright?", I enquired.
"I want something to eat."
"Really? Did you eat all of your dinner?"
"Yes."

I went into Muddear's room to remove her original dinner plate. It was my intention to give Muddear more food considering she was still hungry. That is until I observed that Muddear had only eaten about 1/4 of her dinner.

"Muddear, you are probably still hungry because you did not eat all of your food. Why didn't you eat your dinner?"
"I didn't eat it someone else did! Why would I eat a plate of food that was eaten off of by someone else?"
"Muddear, no one ate your food but you. No one is upstairs but you."
"Don't you think I know what I ate or didn't eat!"

So, what do you think I did? I took the original plate - removed the food and placed it on a new plate (different color), then gave it back to Muddear. Thank goodness, she didn't know the difference and gobbled up everything!

I wonder who she thinks ate her food?
