I have! I was friends with another one, back at home. He's... well he knew my ancestor from like two thousand years ago, so I figure that he's probably over that age. He owns a casino-- isn't that neat?

[ but that's not the point here, is it? if the issue at hand is that subaru doesn't think that it's a good thing for a human to be friends with a vampire, then flat can fix that right away. ]

People like you are awesome. Sure, the bloodsucking thing is pretty inefficient if you ask me, but there's not much that you can do about that, unless you start photosynthesizing the moon or go vegan. [ he shrugs ] But if I am your first friend, then it's a big honor because I'm your first! It's like being a pioneer.
