Dont use mumsnet often so please bear with me.
My older sister is organising a surprise party for her husband next month and has sent me and invite, problem is I have hanging out with them and know it's going to be a huge inconvenience for me.
Firstly, They are obnoxious drunks who always end up in heated arguement with each other and those around them (not me though) their friends are racists and I struggle to have conversations with them, I am also expected to drive around getting things for the party and helping out with her young son. Plus, they live in a remote area so generally stay at my house (in a large town) when they are out and are terrible house guests. They smoke in my living room (I'm an asthmatic non smoker) drink all my alcohol, use every glass and dont clean up after themselves. The last time they stayed up to 4am arguing and listening to loud music after I went to bed despite me asking several times for them to turn it down and go to bed.
I've spoke to my friend about it and he has told me to say I'm sick and not go as they take advantage of me. My mum has said that I should just tell her (my sister) how I feel but I dont want to cause loads of drama. AIBU? What should I do about the party and inevitably them wanting to stay at mine?
