Original Commentary
Why not just send it as a mass email? Perhaps there is an old policy demanding there be a hard copy of all memos... perhaps, because Robert has to do tech support for these people, he knows most of them don't know how to check their work email, so this way is just easier overall. -Isabel

Modern Commentary
In panel 2, Sandra has no idea who Robert is. Sandra just assumes that she ought to know and nods along. - Terrence
