This means that a friend who helps you when you really need help is a true friend. Basically, the idea here is that when someone is going through a tough time, a true friend will be there to support them. Because they provide help in a time of need, they show themselves to be a real friend. It’s good to have friends, and it’s even better to have ones that are reliable. Unfortunately, being dependable is not everyone’s strong suit, and some people might even flake at times when they’re needed most!
