I myself was unceremoniously dumped by a Pilates teacher with a private studio behind Portobello Road. It started well - she approved of me and, I imagine, my Filofax full of potential referrals. But then, during one session, I yawned, which is tantamount to falling asleep at a dinner party. Soon after, she sat me down and said, 'This is not working out.' I was cramping her style. My slot had already been promised to someone else. To this day I feel nervous when I see her (she always blanks me).
