you don't even take your shoes off when you come inside anymore.
you knock hesitantly at the door, and hope that you are greeted by anyone other than her.  
wiping your shoes off thoroughly on the mat before entering, making sure to leave no trace that you were even here.
if you do see her, just a nod of the head and a tolerative smile.
but you don'y ever take off your shoes anymore.
i guess that's because you aren't really considered a guest in the home that you wrecked.
i guess that's because it doesn't make things awkward every time you leave again.
i guess it just makes it easier to walk in and out of the door every time, without having to think too much about what you are leaving behind.
i guess you just want to constantly remind me that you are only here temporarily, never to stay again permanently. That you can just pick up and leave whenever you please.
i guess that's just it.
too busy to be bothered.
too absent to take off your shoes anymore.
