Mom: Do you want a little more coffee?
Me: Mmmmm, not right now, thanks.
Mom: Well there's a little left....
Me: Go ahead and drink it, I'll make more if I want it.
Mom: Well I don't really want it.
Me: Then don't drink it.
Mom: But it's turned off.
Me: Then turn it back on.
Mom: But there's only a little left.
