Managers haven't put the IT request in for a laptop for you or they have but IT haven't actioned it yet and you wait days before you can log in. Or you do have the equipment but no log in ID.
Forgetting peoples names because you meet a lot of people in one go. But they are only meeting one person and easily remember your name = guilt about not remembering and awkwardness to ask again.
