quarterinch's blog post - looks are deceptive

My personal trainer is a really pretty woman with a figure like Butterfly but she is 40, she speaks so nicely to me, smiles at me but I can only conclude she is a sadist. Her name is Tina (the Torturer) and for the one hour session I feel like an absolute blubbering wreck, my legs feel like jelly (45 squats, chin up, chest out), 2x15 min on treadmill, 2x15 on the pedalling machine, then 45 pulling the handlebars down to the chest with 25lbs then 45 dragging the bar thing from the shoulder to the front and in between walking up and down to cool down.
Is it an acquired thing that women can smile at you and all the time make you suffer for some obscure perceived wrong that another male has done in a past life? Does it take training for a woman to smile so sweetly and inwardly think "I'm going to stick it right up this smug, overweight bastard".
I am not dead yet, because I haven't heard the death rattles but I don't feel far away and I don't need to go to the gym until tomorrow, without Tina. I feel very disillusioned, I always thought a kind sexy smile meant "I like you" how come it has taken 66 years to find out the truth.
