Mmm... perhaps not in quite so literal a sense. But I have extensive experience with leeches, siphons, and creatures who hurt those who are just trying to help them. I have also been a potato. Have you ever been a potato? I highly recommend it. It is a worthwhile life experience.

That was sarcasm. In case the aliens who created you did not program you with sarcasm. Which would mean your question about humans was entirely earnest and non-judgmental.
