My nephew has a little lisp, which comes and goes. He is unable to pronounce the ‘sh’ sound, so ‘shoot’ becomes ‘soot’, ‘shore’ (or ‘sure’) becomes ‘sore’.
He was just playing a game on my Galaxy phone when he asked his mother, “Mum, what’s a mission?”
Of course, that came out as ‘mis-on’.
His mother responded, “ Well, you’re meh son!”
