What shape would boggart attain if you were in Remus Lupin's class?

I'm not sure, probably people laughing at some failure of mine...

I would say reptiles but I realize I am missing something afraid of death and suffering. It may make me seem weak but it's true. I can't stand watching people die real life nor can I stand watching people suffer.

Either a giant tarantula or a demon

I've a phobia of heights, so maybe it'd become a height.... not sure how well that'd work, though.
