Lighthearted, and we've both said sorry now.
Told DH I have a feeling I might be coming down with tonsillitis (not covid, did the LFT), and he said 'you're speaking it into existence, if you just ignore it it'll go away'. Later that day he comes home from the park saying he's pulled his back lifting DC onto his shoulders, so I go 'you're speaking it into existence'. He got the hump, walked up the stairs slamming every door. I was being a bit petty, but he should be able to take some of his own expert advice now and then. So aibu, or him, or both of us?
