He's cute, but frustrating

Ty and I were driving home from the store today, rocking out to a little "Snacktime" by the Barenaked Ladies. Against my better judgement I let him hold his cup of water that we got at McDonalds. We were driving along and singing when I heard a distinctive thunk.

Me: Ty, where is your water?
Ty: (singing)
Me: Ty, where is your water?
Ty: (singing)
Me: Tyler, where is your water?
Ty: What? I singing.

At least it was only water because it was everywhere.
