But their brow furrows and they frown, clearly not very pleased] You could have asked first. [Honestly the only reason they're even allowing this is because they were curious on if a human could hurt them anyhow. So far it didn't see like it, though the powder coming off is a little annoying, even if it's only a thin line.]

Please don't do that much, I don't know if I'll be able to find powder to repair it.
