I've actually started wearing short sleeves and showing my tattoos in hospice visits and it has gotten UNIVERSALLY positive reactions from patients, families, and nursing home staff.
One little old lady who is nonverbal likes to pet the chickadee on my upper arm like it's an actual pet bird.
I really want to do a version* of modest dress just as an external symbol of my relationship to god, and if that is what I want to do I feel like it should start before divinity school, but I do worry it would unsettle some people.
*I don't think I can give up pants.
