The following conversation took place earlier today as we were getting in the car.
Ethan: We're going to go see Grammy and Papa.
Me: No, we're going to go drop Mommy off at her workshop, and then we're going to come back home, and we're going to have fun at home.
Ethan: Then we're going to see Grammy and Papa.
Me: No, we're not going to see Grammy and Papa today. We'll see them soon.
Ethan: We're going to see Grammy and Papa tomorrow!
Me: No, we're not going to see them tomorrow.
Ethan: We're going to see Grammy and Papa yesterday!
Do us a favor: post tomorrow (or yesterday) to let us know how a temporal anomaly feels like.
