Actually, you're not so dear.
Once again, you were walking up the street, reading your newspaper, with your leashless dog lagging behind. This is the same dog who got into a staring contest with my dog (leashed, thank you very much) on one occasion, charged across a neighbor's lawn to get to her and to me on another occasion, and dragged your daughter down our street to reach us on still another occasion. The last incident was particularly galling because your child's clearly clueless grandma was smiling idiotically the whole time.
I managed my dog, who frankly has no love for yours. I crossed the street, got out some treats, waited behind a car out of your dog's view, and fed the treats to my dog. Your dog still had seen mine, and was performing her customary stare. At that point you saw me, and stopped long enough for your lallygagging pooch to catch up to you. I kept feeding treats to my dog until you and your dog passed beyond where we were hiding -- yes, hiding.
And I've been nice to your dog. On several occasions when she's gotten loose, I've brought her back home. I've put her back in her yard, closed the gate, and put dumpsters in front of it to block her in . On one occasion, your next-door neighbor -- who, by the way, is deathly afraid of most dogs -- helped me. I've left you notes, asking you to please secure your fence. Not a peep from you, though.
I'm tired of having to cross the street to avoid you and your dog. I should not have to hide behind a car with my dog because you are too pig-headed to leash your not-totally-dependable dog properly. I should not have to stop your wife on the street to ask her to ask you to leash your dog. I should not have to convene an inner debate over whether to risk a confrontation with you (because you are about a gazillion feet tall to my just barely 5' 3") to just get you to comply with local leash laws.
Did you see me staring at you, douchebag?
