Wait 20 years. One day, while telling a life story, look around. You'll find someone rolling their eyes at YOU. Doesn't matter how much you try not to, you'll be there, some day.
Or....you could learn to be respectful to your elders (a long forgotten talent for your generation). Smile, nod your head, and hope someone will be kind enough to act the same way to you, 20 years from now.
