Have you ever been told, maybe while house hunting or visiting a friend, that the train right across the street is no big deal? Eventually you get used to it and tune it out. I happen to know this is 100% true because our second house was right across from the Amtrak tracks, the same ones that will take you from Winter Park all the way to Washington DC. We got a lot of fast, express traffic and with the exception of the demented conductors who blew the horn from the second they were within earshot to the second they left it, we eventually tuned the whole shebang out.
I do this with the girls too. I can totally tune out the fake, just-let-me-have-my-way cries and whines. A skill that Wayne says is annoying to others (him included) who can't pull it off with such adeptness.
The problem is, they know. It's like they possess a secret power and can sense when I've tuned out a sound. Suddenly the ol' screech changes just a few decibels and becomes more of a squeal and bam! I'm paying attention again. It goes from background noise to clawing fingers wrapping themselves around my brain.
These children are crafty I tell you. I wonder if they're sharing notes . . .
