I’m probably going to jinx myself now, but same here.
I had an absolute stinker of a cold January time, but constant negative LFTs and 2 negative PCRs - I genuinely thought the first one was incorrect so did it again and it was still negative.
DD1 had it last summer but she was away at uni, the rest of us (DH, DD2 and I) have never tested positive.
Half of DD2’s college class were off with it a little while ago - she wasn’t unwell and tested negative the whole way through.
I’ve been exposed to it numerous times and not been unwell or tested positive.
DD2’s boyfriend had it earlier this year, DD2 had been around him, he’d been in our house, our car, etc and none of us seemed to get it (none of us unwell and negative tests)
My parents stayed with us for a week, 3 weeks ago. On the way home they started feeling a bit shit, both got positive LFTs the next day. None of us had been unwell before they came to stay or since and negative LFTs for all us.
Weird!
