To the woman on Capitol Hill who rammed full force into me while I was walking down the street on my boyfriend's arm: No, I didn't see you there, and I could not, in fact, watch where I was going, but I did hear the direction from which your stream of invective came. You see, that thing I was holding in my hand, the hard thing that hurt you when you smashed into it, right before you screamed obscenities at me? That was my neatly folded white cane, which I don't typically use when I'm walking with someone sighted on a crowded sidewalk. The very, very dark glasses I was wearing might also have given you a clue—which you desperately need, since you were still yelling as I walked away, apparently unaware that you were at fault. I hope you're a decent human being and that you grow up, pay attention, and knock that chip off your shoulder before you do someone some real damage. Otherwise, I'm curious: What's your next big adventure? Wheelchair tipping?
