Last year, on bonfire weekend, my neighbours set off a good few fireworks in their back garden.
I was a little irked that they chose 'lift off' to be right next to our shared fence (rather than next to the bottom fence which back onto a sealed off strip of waste ground).
Also frustrating was me having to go round my garden picking up the 30+ firework remnants the next day.
Other neighbours in the cul-de-sac let off fireworks too and there were 10ish I spotted and eventually picked up - they're big too! Foot long sticks most of them.
To note, if they knocked & said 'your garden's covered in our fireworks, is it okay to pop round and remove them?' I'd probably say 'it's fine, I'll pick them up and drop the bag round for you to pop in your bin' (I'm sure some will think that petty but our wheelie bins are tiny! & only emptied every other week... I need all the room I have.
so ... AIBU To expect people to pick up their own firework remnants?
