So I have just done my daily Covid test and it has come back positive, husband has done one, the same. I have messaged my mum and brother who were with us on Christmas, my brother had already tested positive this morning and was on his way to get a PCR when I messages, my mum isn't showing on lateral flow yet but wooe up with stolen glands in her throat this morning. My parents in law have ordered tests as they run out, SIL 1 tested positive last night and has a PCR booked for this afternoon.<br><br>It now transpires that SIL 2 is almost certainly the source, she said she had tested negative on the morning on the morning of Christmas day before she came to ours, but it now turns out she had not tested since last Wednesday, her boyfriend has Covid and she has been visiting him whilst he is in isolation. She spent the whole day with us, as well as boxing day. No one else in thr group has been a contact, my in laws were isolating and paranoid about testing as MIL has an operation in the first week of January (which will be cancelled if has Covid), my brother worked from home for a week before Christmas and didn't meet anyone else, my mum only met with my household and my brother in the week before Christmas and SIL 1 worked from home and didn't meet anyone else in that week. SILs flat mates are also now all positive, it turns out she told them she was only visiting her parents, not her Covid isolating boyfriend, some of them now suspect that they have now spread it to their wider families as well.<br><br>So my MILS operation next week will almost certainly be cancelled, my mum can't risk going to the theatre tonight that she has been looking forward to for months, my brother is stuck at home for 7-10 and can't visit his best friends newborn son, my kids can not go to the special event tomorrow that they have been hyped for since we told them on Christmas day, SIL1 was due to spend new year with friends and is now in isolation and SIL 2s flatmates all have to isolate and have potentially infected their families over Christmas. SIL 2 is coughing like a chain smoker but refuses to get a test and has this morning gone to see her Covid boyfriend again. <br><br>She is 41 so not a daft teenager, she thinks she has done nothing wrong by lying about testing negative, infecting 10-20 people, repeatidly visiting someone in isolation and that having both minor and major implications for many people. <br><br>My FIL has just kicked her out of the family group chat (he is incrediblyupset about MIL potentially missing her operation as it has been delayed multiple times since April 2020), my husband is refusing to answer her calls and I am absolutely fuming with her.<br><br>AIBU to not see her side of it?<br>AINBU for everyone being really passed of with her?
