What are your theories behind the "Don't" note?

When Midge gathers with her college friends, they open old bottles that contained a message from their younger selves to their older selves. Midge's note simply said: Don't.

My theory is that Hedy (Gordon's wife) gives the full sentence later in the series when she tells Midge: "Don't. If the credit's yours take it. If it's not take it. That's what the boys do".

What do you think?
