Well now Dursty,having consulted the Big Book of Sins Against the Planet,I find that your little episode does not even register. What you did could not have caused any harm whatsoever and you are in the clear.So all you have to do now is be aware that airsprays and such items are not really needed and we can live without them.And don't you go beating yourself up over little things,looking after your environment is a nice thing to do,not a punishment.
