Actually, consuming rust isn’t poisonous unless you consume it in major quantities (a bit of rust from a pan doesn’t qualify as such)— in small quantities, it’s actually beneficial to your health. We need iron for the proper functioning of our bodies and rust is iron oxide. So I’m pretty sure a bit of rust won’t kill you, it might even do you good.

As for being excellent at picking presents, given what you stated about rust and pans, I’d say you might also excel at offending people — you are great at criticizing and judging under the guise of giving a “gift.” Maybe think about that too.
