<human>: Before I go to bed I make sure all windows and doors in the house are locked. Also, before I close the doors to my room before bed, I check my closet. The only room I don't check anything in is my mother's because she always goes to sleep before I do. Sometimes I don't check if the windows are locked and am satisfied that they are just closed all the way. I don't feel that someone is specifically out to get me, but I look just to make sure no one or nothing is there before I am stuck in a room. I do watch a lot of crime shows but honestly I've been doing this for as long as I can remember, even farther back than when I started WATCHING the shows.

When sitting down I won't sit in front of windows. In my living room I sit in the only part of our couches that is in a corner, it's near a window, but not placed in front of it. 
When I drive I will not roll down any other window all the way but my own, all the other windows only get a slightly big crack.

Also when I packed my room up for our move we just made, I put all of my books(at least 7 medium sized boxes) perfectly into their boxes. I didn't redo it or MAKE them fit, it's just how I put them in that they all happened to fit perfectly to where they wouldn't move around and the box closed normally. 

Some people say this is OCD behavior but I would imagine OCD would be more extreme. There are other examples that are too complicated for me to explain right now but I would be willing to discuss if anyone has any specific questions. Also, wouldn't OCD then affect every aspect of these things and my life? My every day life is completely normal except for these few weird things. 

So my question is this - Does anyone share these behaviors? Does anyone do something that other people think is weird so far as a routine goes?

Provide a brief overview of the text.
<bot>: I always check out a room or vehicle before I lock myself into it and check windows and doors before I go to sleep. Does anyone share this with me or does anyone know why I do these things?
