Are you the only neat freak in your family

To a certain extent - I'm not having meltdowns when a crumb hits the floor

I think so.

Yes. I hate touching anything grimy and end up washing my hands excessively throughout the day to prevent germs or my hands feeling dirty. It also really bothers me to have things messy and out of place. The rest of my family is the exact opposite unfortunately...

yes
i put toilet paper over every toilet seat including the one i have at one that i only use

most of the time yes. I hate living in filth
