DP has just managed to burn the base of our steamer and nearly set the kitchen alight.(3 tier metal steamer on gas hob)
This is apparently my fault
I had prepared all the veg etc in the upper 2 layers and put the whole thing on the hob
I usually fill the base with hot water so had left it empty, and instead filled the kettle and put that on to boil
Said to DP 'could you put the steamer on' in passing when I was off doing another thankless repetitive domestic task
he switches on the gas but doesn't add water/check if there is water in it
(He usually puts cold water in the steamer and lets it boil there)
so we now have a superheated pan and singed veg
and are both totally convinced it is the others fault
We have agreed to abide by the overall opinion on AIBU as to which of us was unreasonable.
