Some kids have imaginary friends. My sister had one that lived in a hole in the backyard. But my children take it one step further.
They have ghost friends. Macy's is named Camilla, and Kaylin's is Albert. They went with us to Walmart tonight, and I got yelled at twice for putting something on top of the ghosts in the shopping cart.
Then on the way home, Albert rode next to me in the passenger seat, while Camilla was in the backseat with Macy.
Hopefully these are nice ghosts.
