How friends take care of each other

I think friends should take care of each other by talking things out. I think this because it is how I take care of my friends, and it is how I would want them to take care of me. My friends can tell me anything because I will not judge based on their problems, I would hope they do not judge me either. I personally bottle up my problems if I am not able to talk to my friends, even though it is a bad habit. However, it always helps to talk about it.
