Warded to Remus
Naive, aren't you? One, I was 'dead' for years. I can arrange for us to meet and no one would ever know that you're meeting me. Two, do you really think that Sirius would care if we're having drinks in public or private? Three, private is only harder to explain if you get caught. I don't get caught.
I told you, I'm here reading books. I must have gone through half of the library already. I'm free every night. Or morning. Or afternoon. Merlin, I need something to do other than potions and reading. And before you say it, I'm not getting a job.
