Flatmate is v lovely but also v big on sharing friends e.g. When her friends/family come over, she invites us all out to spend time with them, likes us all going out for drinks in the eve etc etc. I Iike this too so all good!
Her mum is coming to stay shortly though (in our house) and she has mentioned us all socialising together a few times now. I would love to meet her mum but equally have a few weekend plans of my own and unfortunately lots and lots of work to do (I'm a student).
What can I say without sounding rude or standoffish? I'm also a bit of an introvert deep-down and need time in my room chilling - can't be around people 24/7 especially after long work days!
