Benadryl

Hubs:  Let's go do it.
Me:  I just want to sleep.
Hubs:  I'll be quick.
Me:  No, seriously.  I just want to go to sleep.
Hubs:  Well, if we time it just right. . .
Me:  Here's an idea: I'll take an extra benadryl before I go to bed.  Give me about two hours, and then come on in.  I won't even know you're there.
Hubs:  I'm getting tired of doing that.
