I'd probably choose the Invisibility cloak. It doesn't seem to have too big of a flaw compared to the other two. And I could escape from awkward or dangerous situations.

If I could be a witch. My dream job would be to a healer or a historian.
I am interested in History (im doing a minor in Modern History) and I like to care for people/use potions.
I probably wouldn't be able to do both though, because they have different requirements.

I would be similar to Hermione Granger and Madame Pomphrey or Professor Sprout.
I enjoy books, I am interesting in the application of magic in healing and I like using plants in potions (when I learn how to)
