Some days I'm brave enough to front the cretins, others not.
I still smile at the horrifed/mortified expression of a man who said to DS, "you're a big fella to be in a buggy, you should be walking" (he was only 2 at the time and quite small for his age, so I'm a little confused)
To which I put on my sweetest smile and pollyanna voice and said, "He is isn't he. Sadly he has a rare genetic disorder that means he probably won't ever walk or talk."
You could have fried an egg on the mans face, he couldn't apologise enough - but I bet he was a little more thoughtful in future.
