What is the meaning of tracy lawrence find out who you friends are. whats the meaning of it?

When i hear this song, it means to me that when you're in the moment when you need your friend the most, you will find out who is truly a best friend. They will be the ones that will race over to you in a seconds notice without any explanation. It also means, that when you are popular, everyone wants to be your friend. if one day you slipped, and weren't popular anymore, you would find out who your friends were by the ones that stuck by you.
