My dh became convinced dd's boots 'were definitely not hers' because they had the fluffy top turned up, so you could not see the fluff. Fair enough dd thought the same - but she's 3, not 43.
Nursery workers say it is not uncommon and appears to be a Dad Thing. I am disapppointed in dh as he normally could pick dd out of a line up, recognise clothing and toys, knows what time bedtime is, remembers to feed her etc.
YANBU.
My dh would have at least noticed that the anorak didn't fit.
Leave him!
