You walk into class one day on a warm 34 degrees Celsius day wearing shorts.

Oh dear... You are wearing shorts. You know not to wear those, its apart of the school uniform policy. I open the cupboard up What size are you in joggers?

Oh, I am a medium, but 15 - 16 should do it.

Here! I hand you a pair of 15 - 16 sized grey 66% polyester, 33% viscose elasticated high-rise school trousers Go change into them please, I do not want to catch you red-handed in those shorts again.
