Time Travel

Listening to my girls as they are having a conversation.
"That's easy, just go back in time and get some more".
"Ok, how do I do that?"
"I don't know, how about walking backwards."
Giggles.
"Yeah, walking backwards."
This time with belly laughs. And now they walk out of the room backwards. Bumping into things. Saying, "Don't stop now it's the wrong time!"
