If I tell you now, then I don't have to worry about forgetting to tell you later.
You're all getting a hug for Christmas.
It's self administered, and yes, it comes in your size.
You can use it when you feel it's most appropriate, or you can pass it on to someone else, if you want.
It's not really up to me to say, just as long as you enjoy it.
Okay...
Good...
Well, right, go back to whatever it is that you were doing...
