I have always been scared of dying in a fire. It's my main fear and to mitigate this fear and help me feel safe (also because its something I was told to do by the fireman who visited our school) I keep a towel and bottles of water in the bedrooms so if a fire does break out, I can soak the towel and put it against the door to stop the smoke coming in.
fire extinguishers wouldn't be able to stop smoke coming into the bedrooms so that's not an option.
DH has said he's sick of seeing bottles of water everywhere, it's 2 under our bed hardly loads. I haven't got any in the children's room for obvious reasons but I feel bad and might stick some on top of the wardrobe just incase. They mostly sleep in my room anyway though so it's not a big deal.
I have said I'm not getting rid of them because it's hardly an invasion of space sat under the bed, and it could save our lives if a fire broke out.
Aibu to keep water under the bed?
Yabu - you don't need water and towels
yanbu - better safe than sorry
