To our neighbors' dogs (whom he throws bones over to several times a day):
"I'm sorry Cooper and Sam, but we have another dog we got from someone else's house that we have to take care of. But when she dies, it will be okay because I can still play with you guys."
"I have school Monday, Tuesday, Wednesday, Thursday, and Friday. I can't be with you during that time. But I can play with you in the morning and the afternoon. Deal???"
