Am I getting fatter?

Weird thing happened tonight when I put my running shirt on and I started running, it seemed that it did not fit anymore. Now I know I got a large size when I got it but now it seemed a little too tight for comfort! Had the Canadian portions payed their toll?

I mentioned this to Mrs S this evening who casually said "Oh it may have gone in the tumble dryer by mistake!"

That is secret code for " It went in the tumble dryer Jerry"

So there we have it, one of my favourite shirts now needs to be stretched, but how?
