My youngest son walks in my home office, grabs the Apple keyboard, and runs out with it.  I chase him, blurting out, “you break my only keyboard…” I couldn’t finish the threat, because I didn’t have one.  My oldest walks in and says, “Dad, do you have to work?”  “Dad, do you want to watch T.V. with me?”  “Dad…” Or both my sons blast through the office door since I forgot to lock it, or when I do lock it, they bang on it until I answer them.
