Debby: Rose, we are going to Grandpa Jere and Barb’s house to play this morning.
David: Me too.

John: Rose needs more pretzels for snack at school.
David: David too.

Debby: I’m going to take the garbage out.
David: Me too (said somewhat plaintively and reinforced with much patting of the chest)

John: Rose, do you want to help me make muffins?
David: David too, David too, David too!
