No...your sensitivity is one of the many qualities that makes you so special. I would have cried too. That's a very poignant story and now that young man knows the worth and the impact of his story. He will save lives and you encouraged him to travel that path. You did good so to speak.
Culture has it wrong. I wanted and needed to cry at my daughter's graduation but nobody else was and I felt foolish. I won't make that mistake again. When she graduates from college I'll be a proud crying mom.
You're very special.
