I don't know who Mark Grace is, other than he is an announcer for Fox Sports Network. Beyond that, I don't know and frankly don't care. His personal life is his business to deal with.
Also, the older boy is a prime example of how we should live our lives - giving selflessly of ourselves so that someone else may benefit from our kindness. In return, because we have given selflessly of ourselves with the right motives, we will be rewarded for our kindness, just as this young man was. If I am not mistaken, all the kids were invited to the Fox Press Box to meet the announcers and to receive various goodies on behalf of the home team, correct? So, what could have been a selfish moment for one boy, now turned into a bright shining moment for all of them! I see several life lessons in this one simple act of kindness.
