A good friend called me last weekend trying to kill some time while waiting on her chronically late sister, "We live exactly the same distance from this café, a place we meet each month, and 9 out of 10 times she is 30-40 minutes late, it never fails!” My friend went on to share other “flakey” aspects of her sister’s behavior in their relationship such as forgetting dates, not following though on tasks, and so forth.
