Nice way to use my chest

I went to pick up my friend. As I was driving, I remembered that I had to get something out of the glove compartment. Once I reached her place, I put my foot on the brake, my left hand was on my lap, of course seat belt was on and I leaned over to reach the glove compartment. I angled myself so that I would stay clear of the steering wheel.

Well I guess the horn was sensitive and I must have brushed my chest on it because the horn went off. I could have sworn I was nowhere close to it. I'm laughing and the car rolls since my foot slipped off the brake. I didn't have the brake release on. My friend walks up and says "it's not necessary for you to honk." She sees me laughing and I explain to her what happened.
