I would follow your Dad's advice. He has made a very valid point!

I speak from personal experience.

For instance..in the future..I believe it might say..keep you from boarding a plane. I think in the future it is quite possible that those who suffer from mental illness will be added to the "no fly" list.

Believe me..it is a possibility!!
That's just one of the possible scenerios! IMHO.-Dottie
