So me & DH live in a tourist resort and have lots of visitors, especially over the summer, which we love and generally enjoy. Our friends daughter is staying with us along with her boyfriend for a couple of weeks and it's been quite stressful as she is incredibly lazy . The boyfriend is slightly more pragmatic about helping out . Anyway I've been biting my tongue for the last 9 days as I cook, clean & work while they lay about by the pool, leaving rubbish, plates, cups and cigarette butts ( we are completely non smoking and I hate smoking ) around where they have been sitting. I have mentioned, "can you bring your stuff into the house" etc but it's every day they need reminding. Any way they went out today ( I drove them for an hour to the destination but had to come back to work ) and left them to sight see. I just popped my head into the bedroom to make sure the Aircon was off as they has a habit of leaving it on, anyway in the middle of the rug is a big pile of sand and rubbish ( looks like she tipped her bag out on the rug)
I took deep breaths and thought, they will clear it up when they get back ...no harm done 
. So after picking them up later in the day from the sightseeing...it's now been 5 hours since they returned and they have made no attempt to hoover up the mess...I literally want to throw them out and say go get a hotel, to be so disrespectful when they are having a free holiday. It's made me think I never want anyone else to ever stay with us . Her mum is a very dear friend and I am at a loss as what to do . I will never have them back again but how do I get through the next 3 days without loosing my shit - help
