Help (old) friends.
（昔からの）友達を助けよう。
I don’t have many friends. When it comes to my close friends, I have only a few.
When any of my close friends asks me for help, I’ll do whatever I can do for them. If they don’t ask me for help – even when they get in serious trouble – I try not to bother them. Sometimes it helps them more than doing something for them. I know this because I know them very well – maybe more than what they know about themselves.
Just be on someone’s side is not easy to do. We tend to get involved in no matter what – even when it’s not appropriate. We need to know what our friends want from us, not what we want to do for them.
