Letís examine the facts, shall we? I rode past you & that frightened you. I didnít hit you or make you crash, I simply rode by you. Based on this obviously horrifying event, you now suggest that I ìget a bell, get a horn or say somethingî. Really? Youíve already demonstrated a propensity to be frightened by the most benign of actions (me riding by you) & now you want me to introduce some sort of early warning mechanism? Really? Great, youíve sold me & on your suggestion, Iím going with a bull horn. Next time I come up behind you Iím letting loose with that SOB. I suggest you get fitted for some depends (if you havenít already done so) because based on your first reaction, this next one is going to be something to tell your grandchildren about!
