What Are Some Blatant Signs of a Bad Friend?

If you're asking about emotional or something, well that's a lot. A bad friend can be blatant emotionally, socially, psychologically etc. So far what I can only think about is when they tend to be offensively judgemental about almost everything. It gets to the point that they air this out aloud, already hurting feelings in an insensitively unaware way. That's got to be the saddest behaviour. But if you're asking about this in a more physical sense (or either way), the signs depend on a situation and story anyway, but what I've stated above sounds general and I can't think of a specific story so yeah. And this sounds like something negative to talk about so. .. just probably Google it. Hehehe cheers
