Constability 

The ability to be consistent, without flaking out on those who have come to depend on you resulting in lost opportunities in personal, private or professional relationships.

Drummer: "So are you and your original guitarist gonna get your old band back together...?"

Bassist: "I wish bro. He's a killer guitarist & songwriter, but he flakes out and wont show up when he says he will. He has no Constability whatsoever man. I can't waste my time with him"
