There are a lot of things we might look for in a good friend - but listening is the most important, according to experts.
One relationship expert told Best Life Online, "The top trait that both ignites and sustains friendships is the ability to listen to one another because it is at the root of connection."
It's not just listening that makes someone a true friend, either. Experts say being a "good" listener means listening without judgment. It doesn't mean you agree with that person, but it shows that you can be there for them.
Another relationship expert said even if you think your friend is making a mistake, "resist the urge" to tell them that "because it might not be a mistake to them. They have their own goals, dreams and desires in life. Criticism is a poison pill."
