I hate seeing people throw litter out of car windows, and chewing gum on the pavements is awful too.
But little old ladies with quavers I'm not sure about.
I agree that littering is bad, and I agree that you shouldn't let her off and even apologise to her just because she's old, but I have dropped crisps and not picked them up as dogs and birds eat them, and I throw crusts and apple cores for birds and such too. But I don't really think of that as littering, more a form of re-cycling. But if I drop anything else I pick it up and put it in the bin.
Maybe if littering could be re-defined and made more place and danger/mess specific, life might be a bit easier?
Also will this smoking ban in public places will mean a lot fewer cigarette ends in the street, or will it make it worse as all those people who can't smoke inside anymore all stand outside smoking instead?
