Remember 'that kid' at school who was perfect. Not for them the covering of school books with old discarded wallpaper as daddy's PA would laminate them, thus helping to ensure that consistent academic success was achieved without the need for genuine contemplation.
Not for 'that kid' coming off a muddy soccer field on a winters morning, legs purple with cold, snot pouring mouth bound, caked in three quarters of the field, with a sending off, an own goal and parental disappointment as the main reminders of the match. Oh no, 'that kid' usually came off the pitch shoulder high as supporters and team-mates celebrated his hat-trick that ensured a win that masked your ignominy.
As for mud? Simply not 'that kids' problem. His return to the dressing room rarely warranted a shower, although he had one, complete with raspberry shower gel, because he was so damned perfect!
