Am I OCD?

It's a chilling feeling when you are in the bathroom stall at work and you can hear someone leave the stall they were in and walk out of the bathroom without the faucet turning on. This is why I and others I work with, use papertowels to cover the door handles we use in the office. This is also why I'm always very un nerved when someone needs to use my computer. Ew...
It's also quite disturbing to hear someone in the stall brushing their teeth and peeing at the same time. Really, that's not a huge time saver! Take the extra two minutes to brush your teeth separately!
