Friends come and go?

Friends come and go if your realize it. There is always new friends coming along if your willing to accept them into your life. What about old friends?

Mindset changes people on how they wanted to live, or socialize. A little argument changes the relationship and it won't go back as it was before. What kind of friends do you want? Kind? Helpful? Funny?

As we get older, our ways of thinking changes. Do you still care for them as much as you have when you were that close to them before? Some do, but some don't appreciate of what you've said and done.

Is there any such word is "best friend" to you? For now, there's none for me. Do I care for some of them? Trying NOT to.
