The other day I was in a cafe and there was a young mother at the next table. She screwed up her nose a bit and said to her son, about 11 years old, "have you had a shower today?" He was quick to say yes, but I quickly glanced at his mother and she was looking doubtful. One of the boys I used to hang out with when I was little told me once that all he had to do was wash his knees and his mum would think he'd had a wash. There are always tricks people try, to avoid getting in that god-damned shower.
