The air conditioning man

So as everyone has already heard, our air conditioning unit needs to be replaced. Grandpa's neighbor Dave is doing the work for us, with Grandpa's help. The girls have been seeing Grandpa come over to help with the air conditioning unit. But of course, Grandpa is not over to play with the girls but to ensure that we don't swelter for the rest of the summer. So, I try to explain this to them to which Gaby responds:
Gaby: "I don't like the air conditioning man"
Me: "Why?"
Gaby: "Because he doesn't let Grandpa play with us."

Poor Grandpa!
