It's nice for children to help their parents out
Hank is at home just relaxing when his dad Tony calls him and asks him to come over and help him do some garden work.
Hank wants to respond to his dad's request for help.
Hank tells his dad that he needs to change into something less fancy, and he'll be right over.
Hank tells his dad that gardening is hard, and he's relaxing, so he can't really help him now.
Tony is delighted that Hank will help him and relieved he won't have to do all the work himself.
Tony is annoyed that he can't get his son to come help him when he needs it and hangs up.
