My 4 yr old grandson Drew was riding in the van with his parents when he overheard them talking about electricity (probably the bill) He wanted to know what electricity was. My over achiever son in law went into a detailed description of what electricity was and how we use it. Drew was quiet in the backseat for a few minutes, then very seriously asked,'' Do it have eyes?" No one laughs when I tell this story, but for some reason it cracks me up! My son in law seriously trying to explain the scientific theory of electricity and 4 yr old Drew imagined it as a creature! Maybe only a grandmother would laugh, I don't know, but it still cracks me up!
