Mommy's food is the best food

After he saw me making a bagel with cream cheese yesterday, Moo requested a burrito for his lunch. I heated one up, cut it, let it cool a bit, and served it with milk at his table. Two minutes into eating it he came over and stuck his finger in my cream cheese, asking, "Will you eat this?"

I said I would and then popped the last bite of that half of the bagel in my mouth. He tried poking the other half and asked again, "Will you eat this?"

OMG, yes! I am going to eat it! Leave me alone!

I actually said something along those lines. I asked if he was going to finish his burrito and he said no, looked mildly offended, and then tried putting his fingers in my food again. I told him to go away and he looked hurt. Why does Mommy's food always taste better than the food on Moo's plate?
