Don't be too eager:

“You ready to go back home hun?”

“Are you sure mom?” You are definitely ready to go back home, but you don’t want to sound too eager, so you don’t make her upset.

“Well I was going to take you to a few more places, but I think I want to give you your surprise sooner rather than later. So let’s go back home.”

You silently thank the universe that this nightmare is almost over, “Alright, if you’re sure.” You say, linking arms with her.
