A Mighty (long) Wind

Today we picked up my husband from the airport, and on the way my 4 year old asked me, "Mommy, why do cars have horns?"
My first thought was "It gets the attention of the a-hole who just cut me off so I can flip him the bird."
But seeing as how this was a small child (who I just finished writing about his innocence) I decided on a more appropriate answer. I explained that horns are good for alerting someone when they accidentally drive too close. I added that its also good for when the light turns green but the person in front of you isnt paying attention and wont move. You can honk the horn and let them know the light turned green and they need to get going.
He was quiet for a second and then said "That was a really long story."

Thanks, son.

After we picked my husband up, I told him what our son said about my not-long-at-all-thank-you-very-much explanation of the use of horns, and he looks back at him and says "Get used to it, son. She's got all kinds of long stories to tell you."

Thanks, honey.
Grumble.
Yo! Ive got something to show you! *whack!*
