The two Ethans

Today at camp, Noah (age 3.5) built a farm using the Legos. I noticed that he included a Lego fire hydrant on the farm, and I asked him what the hydrant was for.

Noah: Fire comes out of there. That's how they get died. They're died.

Me: You mean, "They're dead". When someone dies, you say 'they're dead'.

Noah: They're died. I died... I dead them. I died them.

Me: (trying to change the subject) Can I put this here so the cows can drink water from it?

Noah: No. Cows drink milk. From down here. (points to Lego udder on Lego cow).

Me: Um... (decided not to try to explain that cows do in fact drink water). Who's that? (pointing to two almost identical Lego people on two Lego horses.)

Noah: Those are the two Ethans.

Me: Oh. I see they're both sitting on horses.

Noah: They're dead, so the two Ethans can't sit there. (takes them off)

Me: Oh.
