Now that we're using this envelope system, we have to figure out from whence the money will come for any purchase. There's the pet (aka dog) envelope, the grocery envelope, the medical expense envelope, the clothing envelope, and the "fun" envelope.
When I mention buying something, Cliff loves to ask, "Do we have an envelope for that?"
So when I informed him we'll probably go get a Christmas tree next weekend, I didn't wait for his smart-aleck reply.
"Cliff," I said, "We'll go get our Christmas tree next weekend. The dog is paying for it."
