Oh where did I put that thing again? I forgot where I set it the last time I used it, and now that I want it, I need it, it's gone!

Huh? What's that note on the door?

Dear irresponsible owner,

You never seem to remember me until the second you need me, now I'm hiding so you know the lonliness I feel.

Yours truly,  the thing you need

To my needed friend,

It's not that I don't want you, it's that I don't always need you everyday. That doesn't mean what you do isn't valued. When I need you, it's only you I can use. You are very special as well as the job that you do. 

Love, your trusting owner
