Letter to the editor: May I just say how mischevious it is for people to drop their litter on the pavement.

Walking my dog — yes, I make sure nothing is left to indicate his passing — I have to keep my eye on the ground to avoid him stepping into the giant ashtray made by the litter louts.

I actually find these discarded cigarette ends more disgusting than any other mess on the pavement.

My particular bete noire is the thought of them getting into my dog’s ears or feet or sticking to my shoe and treading them indoors.
