I often joke with my kids about being all out of hugs and being too tired to give them kisses and that's why they have to come hug and kiss me instead. They know it's a joke (it's a very obvious one, like my joke about how they all hate chocolate so I should eat it instead), and they play along because it's our own kind of weirdo fun. This morning The Youngest said: "Mom, you can't be out of kissies."
"Because everybody doesn't."
Ah yes. There is that.
