Try this with your kids. I have found that it works quite well for many things. Just this morning, I employed this strategy twice:
Mom! I have a snotty nose!
Well, don't tell anybody, or everyone will want a snotty nose.
Mom! Bird poop on my window!
Well, don't tell anybody, or everyone will want some bird poop.
Every time I do this, the kids growl in disgust and hurl vitriole at my dad: "Thanks a lot, Poppa!"
I get a little giggle each time, the kids give up on me in indignation, and I don't have to respond to every little complaint. Like I said: magic.
