You are an angel too. Kids don't have a lot of control in their lives, and when someone shows them true love, it creates a safe haven in a stormy world. It's the best thing you can do to honor your step dad, pass on the gift he gave you to these children, and I can guarantee they will grow up and keep it in their hearts to pass on again. That you give this love freely and gratefully makes it all the more powerful. You are a wonderful person, Billy, and I'm glad I got to know you.
Now zip it, and give yourself a hug.
