Was on a seaside holiday with the family a few weeks ago and this still makes me go 
.
I was in a shop on the last day and the kids were spending their fiver for a little something for the end of the holiday. They were buying some sort of magic putty stuff and I was in the sweets aisle, seeing if there was any rock or anything for gifts. They finished and then came to stand with me whilst I rifled through the sweets. I dedided they might like a sweet too, as a treat, and there were some great pez's on the shelves.
A woman (slimmer than me and rather prissy) was in the aisle with her kids. I was knee deep on sweets by this stage and clutching all sort, trying to decide. Her kids were looking at the sweets too. She looked me up and down with a pantomine sneer and said loudly to her children "well, I suppose you can have one thing as you havent had your piece of chocolate yet this week, have you".
Thing is, I may be slightly heavy (I have gained a bit of weight after a running injury a few months back) but little did she know, Im a nutritionist and specialise in paediatric nutrition and my kids eat a great diet (as do I)...stupid cow.
