Drive-thru Dilemma

Going through the drive-thru at Wendy's:

Hudson: Husson wants a hangaber, Olfinn wants chicken nuggets.

Me: Olfinn, do you want chicken nuggets?

Oliver: No. Cheese.

Me: You want grilled cheese? They don't have that here.

Oliver: No. Cheese.

Me: Do you want a plain piece of cheese from home?

Oliver: No. Cheese! (Signing cheese this time)

Me: I don't know what you want...(Racking my brain, wondering what he could be talking about)

Oliver: Cheese! Cheese! Cheese!

Me: Oh! Do you want a cheeseburger?

Oliver: YES!!

Me: OK! I'll get you a cheeseburger...I didn't know you knew the difference...

Driving home from the back seat I hear:

Oliver: Mom! Mom!

Me: What, buddy?

Oliver: Mmmmmm.

Me: (laughing) Good! I'm glad you like it!

Oliver: Mom! Mom!

Me: What, buddy?

Oliver: Mmmmm Mmmmm Mmmmm...
