I saw a bumpersticker here in town this past week that read, "Guns don't kill people, drivers with cellphones do." Of course, the driver was using his own cellphone at the time I saw him. *sigh*
Another one I saw: Being hit by someone you love is a crime.
EXCUSE ME? *grumbles many things I should not say*
One thing that really, really, really bugs me is when people mean one thing, say another, and then blame me for the miscommunication. "Well, it was obvious what I meant. You are smart enough to figure it out."

What does that sticker say to the young woman who is driving about with her eye blackened by her boyfriend? You are the wrong one, here, honey. He is right. It IS your fault.
