Yes, love is definately needed.

I believe that a friend can be judgemental as long as they have the ability to keep their judgements to themselves when needed and tell the person when their opinions are needed and called for.

I'll throw this one in the stew. Trust. A friend should be trustworthy. Now some friends can be trustworthy for some things, such as not being a gossip, and others can be trustworthy for other things, such as showing up on time for an event. You have to make the choice there.

Also, a true friend will tell you when you have body odor!
