Man, if that was the worst words I hear, I would be ecstatic. My daughter just bought her own Gown, something like $500 +, Not sure how much of it I paid for.
Worst words I could imagine hearing are, Sir, you need to get your child to St. Judes, I hope I never hear those words and have the utmost of sympathy for those that do.
Second worst would be, we did all we could, but could not save your family.
Man, I hate to be such a downer, but I suggest you go buy her the dress she loves the most, take her out and celebrate, you may not always have that chance.
