So your choice to indulge in "other activities" on the 5th means that people like me have to suffer your selfish behaviour on every other night of the week.
Have you considered the pets in the area? One night is bad enough but just about acceptable because we know what and when but to have to keep the pets locked in for up to a fortnight so that people can "indulge" their whims is not playing the game ~ Tsk!

The question is:
By holding your firework party on a date other than the 5th are you actually joining in the celebrations or just being bloody anti social? EH?
EH?
