I like to think I'd be friends with ghosts if I could, but then, whenever I think I see something I get freaked out and avoid messing with it anymore.
I'm like:
"I think it'd be fun to meet a ghost"
*sees something on the edge of sleep*
*smoke cleanses room and draws protective sigils on all windows and doors*
but then, this is also how I approach relationships with corporeal beings. So I guess at least I'm consistent.
