what do you call the thing you write at the end of a note, right before your name? the exit, the end?

the Librarian's notes are now full of quotidian details (i worked 60 hours this week, i'm about to start recording, i bought a book) and i've lost our ending. before, i could hug his 'ever' or 'yours' and get a little warm. now, it's just - the Librarian. plain, stolid. me.

not 'yours, me'.
just 'me'.
