It's happened to me more than once. Only one time have I actually gotten in and sat down. No harm, no foul. Just a few weeks ago, a woman at work told me that she got into my car and sat down because she thought it was hers. Funny stuff.
I was just having this conversation with my son the other night. He told me that he thought Lennon was a scumbag because he hit women and made his son lose his hearing by yelling in his ear.
I told him that Lennon made plenty of mistakes, but became a better man as he matured - as most of us do.
