So why are so many people of my generation (late stage #boomers) oblivious of mobile device courtesy?

I'm sitting in the waiting area of the tire shop. An old guy (like me), sits down pulls out his iPad and starts a television program for all to hear.

His phone rings. He takes the call on speaker phone and raises his voice to be heard over his television program. Annoyed with his own noise, he seeks a quieter location, walking away from his iPad without pausing it.

His wife is doing fine and will be ready for pick up in forty minutes. Their daughter is still mad her husband.
