Elaina, Charlie and the Perfect Friendship

It is a match made in heaven, really. She wants to constantly pretend that Charlie is a dog. Charlie loves to pretend that he is a dog. She wants to constantly pretend that she is nurturing some inanimate object. He will pretend very well right along with her since he isn't really sure what is alive and what is not. She loves to be in charge. For some reason he lets her take charge of him. She sends him on little errands. He rushes off to do her bidding - happy for the attention. They are both just a tad insane. It works out so well! Today I am thankful for Elaina's (7) friendship with Charlie (2.5). Right now they are pretending that my decorative eggs are some sort of eggs that they found in the wild and are waiting for them to hatch to discover what animal will emerge. Question is...do they actually think the eggs will crack?I am pretty sure Elaina realizes they are pretend. Charlie however, may just play along FOREVER until those eggs crack. Elaina may be smarter than I think.
