Do you remember wearing a school uniform cap ? Probably not but you probably kept one in the quick draw position in a blazer pocket....
Well do you remember the Royal Blue school cap with the golden oak tree ? You'll have to be of a certain vintage to do so. It was only compulsory for First Years and I wore mine on my first day but immediately removed it when I saw that no one else was wearing one. There were occasional cap traps where prefects would hide in wait and then jump out to give you a detention for failing to wear one. Fear of these soon wore off however but the cap stayed folded in my right hand paocket for some time...just in case.
