Thank you!!  I'm glad some people have common sense!! Fatty couldn't seem to understand why I was pissed off that she'd come into my home when she knew she was sick!! I have a severely compromised immune system!! I have to wear a mask just to go out in public and if I'm admitted to hospital then I'm placed in isolation with full infection control procedures for anyone that enters the room!! If I'd caught the fat twat's cold I could have ended up in intensive care with pneumonia again!!  If I'd have known she was ill then I'd never have let either of them in but she didn't tell me until they'd already been here for half an hour (and she was chowing down on her stolen snacks!!) I was furious about the whole situation and my friend and I have had a serious talk about what is and isn't acceptable if she wants to A) remain my friend and B) continue to visit me. I'd rather lose a friend than deal with this kind of shit!!
