Visiting the in laws last night where BIL1 and BIL2 live at home.
They all keep their shoes in the porch which doesn't get locked.
BIL1 asks if anyone has moved his shoe as the left one has gone missing.
Everyone denies moving the shoe.
BIL2 goes to put his shoes on and the left shoe is missing. Everyone denies touching the shoe.
FIL then goes to check all the shoes and found several shoes (majority left, one right) missing.
MIL swears she's not touched the shoes (has form for moving things and forgetting
)
PIL are convinced there's a one legged shoe thief come to torment them 
MIl has decided to move all the shoes inside and FIL is adamant he needs to get some cctv equipment.
AIBU to think someone must be playing a joke and that who would possibly go around stealing one shoe??!!
