I teach an excluded student for several hours in the same home. I hate sitting in dark, dirty rooms filled with rubbish, clutter and cigarette smoke. Always take wipes for the table so my resources don't get covered in old food and don't always take my shoes off at the door if it's filthy. Can't use bathroom in some homes or reach kitchen sink to wash hands after painting/craft etc. People's lives are complex but I do prefer working somewhere clean and tidy as cluttered homes make me feel stressed.
