To Haligonian dog owners who bag their dogs' poop, and promptly leave it on the sidewalk: what is wrong with you?!
If you're not going to throw out the poop, leave it there, it will disintegrate. Leaving the plastic bag there is just littering: why are you making an effort to litter by also making an effort to touch dog poop? Do you like touching dog poop??? Ew!! —Poo-destrian
