Nasty Crabs

Lucy: Mom - Can we go to the beach to see some nasty crabs?

Long pause. Do I even ask her what she means by that or just say yes and let it pass? 

Me: What do you mean nasty crabs?
Lucy: You know, the ones that crab you.

Having a four year old with significantly older brothers immediately raises my suspicions in conversations like this. What exactly did they tell her - that's always the question. And you should hear some of the other things that they tell her, and of course, that she repeats. It's usually at the top of her lungs in the school office, the grocery store, or another public place where I can't run and hide.
