Little Piranhas

What is it with my kids mooching food from people? Both Ryan and Wesley think the food that someone else is eating is far superior to the food they are eating - especially if it's something sweet. I made a lavender lemon pound cake the other day and neither boy would touch it. However, give a piece of that same cake to Grandma, and they descend upon it like they haven't eaten in days. I've never seen anything like it! Grandma was lucky to get three bites before it was gone and both Ryan and Wesley were covered in crumbs. Guess I'll have to make Grandma a cake of her own.
