A horn is NOT for honkin'

I am so confused.
I was taught a car horn was an attention getter.
According to Big Shooter, my Driver's Ed instructor failed me.
Completely.
Apparently I missed the whole lesson on A horn is NOT for honkin'.

I have heard these kinds of statements for over 20 years now:
"A horn is not a play thing."
"It should only be used in extreme emergencies."
"If you touch my horn again...I'll chop your arm off..."

I have listened respectfully and abide by his wishes.
Kind of.
I have occasionally beeped the horn when he's walking in front of the vehicle.
If he is oogling when he thinks I'm not paying attention I've been known to reach over and give the honk a little pressure...then wave.
I honk when I drive away from home just to let him know I'm thinkin' of him.
Things of that nature.

He freaks. I giggle.

But here's where the confusion comes in.

When we see a JUST MARRIED message painted on a car, everyone knows the universal good wish is - honk to wish them good fortune. Will he? No.
When we pass the dude dressed up in a cow costume outside Chic Fil A, in 102 degree weather, holding a sign that says, "HONK, if you love chicken." Does he? No way!
When his face is purple and veins are bulging from the moron driving in front of us does he? No.

But when we see the resident loony dude dressed in his filthy felt Santa suit, perpetually riding his bike around town holding his latest sign, "Honk for Obama", does he? Yes.
Yes?! We have a McCain sign in our yard...
When I look over at him in shock and raise my eyebrows in question he shrugs and says with his crooked grin, "You'd think someone riding a bike wouldn't want to be honked at...".
He's correct of course.

At least he didn't oblige the loony dude's last sign.
Fart 4 free gas.

Love Note to my Big Shooter: Honk. beep. beep. Honk! HONNNNNNK!!!!
