My hand washing is down right now, and I manage to not care about it most of the time. I get very very particular about hand washing when it comes to dealing with the rabbits. If I'm going to touch them or feed them, or handle anything of theirs, I absolutely have to wash my hands, sometimes twice, and I have to dry them on a clean towel.
When I go to rabbit meetings, I see people put lotion on their hands then pick up a rabbit. I want to scream at them.
I don't use hand sanitizer because I have eczema on my hands, and they're often dry and cracked, so sanitizer is very painful. I will not touch the handle of a toilet in a public restroom (I flush with my foot), and I use a paper towel to open the restroom door. I hate hate hate the restrooms with no paper towels, as I then either have to go get a big wad of toilet paper to use, or wait until someone else goes through the door. I also hate when there is no trash can directly next to the door, as I then have to carry around a paper towel (which is now filthy) until I find one, or I just throw it on the floor in the restroom. (Sorry!)
I went through a period of time where I obsessively checked the stove before I left the house. I would check it multiple times, and usually had to go back inside and check even after I'd checked it. It made it very difficult to leave the house, and I was late to work many times because of it.
I have to check the door before bed, to make sure it's locked. Even if I was the last one home, and I always lock it on my way in. Even if I see my husband lock it. I can't sleep unless I make sure it's locked.
