Roles can change before the surrounding relationships learn how to respond differently.

A change in what you are responsible for happens on a particular day, but the people around you go on treating you the way they always have. They are not being difficult; they are running on a picture that was accurate last month. The result is friction that feels personal and is mostly just lag. It shows up in who gets asked, who gets told afterwards, and which old habits keep being handed to you.

Rather than waiting for everyone to notice, say the change plainly once to the people it affects. Then be patient while the new arrangement is learned, and expect to repeat yourself kindly.
