To think leaving stuff on the stairs is a bit dangerous

[BlueCanary]

What is it with people who have piles of stuff on their stairs.

I'd say that about half of the houses I visit (friends, ILs, family, play dates etc) have stuff on their stairs. Maybe a pair of slippers on bottom step, some magazines on next step up, maybe a few toys on the next one, and then some washing/coats/cardys halfway up.

Why?

AIBU to think this is unsafe, and someone could go flying, and really hurt themselves.

I do it all the time so the next time I'm going up I can take a pile instead of the odd thing and running up and down 20 times a day

Depends how wide your staircase is.
