I think he had a choice to leave his child size sex doll at home. It's not like she was going to get lonely.
The kid in the background is trying to figure out what aisle they have them in and if he can talk his mom into getting him one.
To be fair, he wanted a full size adult model but the smaller ones use less materials so would obviously be cheaper, and at his age with his fixed income, he had to make due with what he could afford. We need to take better care of our veterans.
