The concept of Tag-A-Long developed as I was drifting into a moment of nostalgia, thinking about one of them most defining relationships of my life. We've all had a Tag-A-Long at one time or another. That special person who is our number one fan, even if our fan club only exists of one person. A Tag-A-Long is that person who believes in you, adores you, confides in you. and you know what? Chances are, you are that person's special Tag-A-Long as well.
