So great to see your name on the boards again!
Good take on the idea that the difference in his and Lois'age would cause him to act a little strange.
But, I don't believe he would reveal to the world that he is Superman. The recupercussions would be too great. If it were just he and Lois ...maybe. But his children's lives would be in danger and that is not something he could risk.
Again, great story!
