I am a stickler for rules and I have never ever sent anything of my DSs' to school without a name in it. All their uniform is properly labeled with embroidered name tapes and anything they announce last minute they need to take in will have a name hastily added in permanent marker.
Whenever something is missing, I will politely enquire at the office and am pointed towards a huge pile of dirty clothes to rummage through.
So why do a need to put the name tapes in, if no-one has a look to see if the item is named before adding it to the mountain?
