I think that this song is about someone trying to tell his friends that sometimes, although things don't always go as planned, it's important to remember that time spent with friends is the best. It's also saying not to hold back and just go with your feelings, never be discouraged to say what you think.
It also seems like a song about going away and it is the last night he will be seeing these people for a while so they should just make the most of everything and remember all the great times shared.
