SH+There+is+no+wish+your+tongue+can+tell

I believe the line, "There is no wish your tongue can tell" means that their is no greater gift to wish for other than friendship because friendship is the most natural, beautiful, and greatest gift you can ever wish for. This line may help you realize and appreciate how lucky you are to have friends who stick with you through out your most difficult times, and they are people you can always have a great time with.
