Don't worry, I'm not so great at it either. Luckily we don't really have to judge their character right now. At this point, nobody knows who to trust besides their partners, so nobody's going to trust anyone since they won't know if they're wolves. But on the other hand, the wolves will feel safest today, since nobody is specifically suspicious of them. That's why today is important: the wolves will act without fear of being voted out, since nobody's going to agree on a vote one way or the other right now.
