They should listen to you when you are talking about something and give you feedback, especially if it is important. If they do this, you know that they were actually listening instead of just pretending to listen.
Another one of the most important things I look for in a good friend is someone that dosen’t pressure you to do something you don’t want to do. You already get more than enough pressure from others.
As you can see, a few of the many qualities I look for in a good friend are trustworthiness/honesty , hoe kind they are, and how understanding they are in tough situation.
