We live in a semi detached house and it looks like most of the evenings partying will be going on in their fairly small garden which is currently filled with a marquee complete with speakers 
They don't do this all that often, so I'm going to have to suck it up, but their parties go on so fucking long. Last one didn't quiet down til 3ish and the drunken teenagers decided at some point to chuck their shot glasses onto our patio. Not fun for a family with a cat and a toddler!
AIBU to hope their marquee falls down?
