I let a co-worker and a friend use my office when I'm out in the classroom. I don't mind because... well, why not? He has a quiet place to work and I'm not there anyway. Today, I came back to the office and found an EAR WAX REMOVAL KIT in the trash can (I wasn't digging, it was on top). I absolutely hate anything to do with bodily maintenance and gross and smelly things that we produce. I am so skeeved out!!! I thank god it's not toe nails he had to tend to.
How do I tell him that my office is not for ear wax removal?
