Literalism: A Conversation With Luke

After asking Luke to bring his dinner dishes into the kitchen....

Me: Luke, where is your glass?
Luke (looking confused): My glass?
Me: Yes, your water glass from dinner. Where is it?
Luke (still confused): I didn't have a water glass.
Me: Yes, you did, you were drinking water.
[Luke goes into the dining room and returns]
Luke: You mean this?
Me (exasperated): Yes. Isn't that the glass you were drinking water from?
Luke: Mommy, this isn't a glass, it's a plastic.

Currently feeling: silly
