I do actually know I'm being unreasonable here.
First thing this morning hubby made me a cuppa (as he often does). Sorting out the kids I didn't get to touch it (as often happens) and then he suggested I go and get in the shower first.
I just got downstairs and he's gone upstairs to use the shower. I saw the tea on the side and just picked it up and downed it.
Turns out the original cup of tea had gone cold so he'd very kindly made me a fresh one (this has never happened before). I've totally burned my mouth and throat 
AIBU to be a bit grumpy with him?
