I was doing the exact same thing in the beginning when I discovered I was allowed to email. But then I kind of learned and started to trust that T will read and respond to every email I send, even the most silly ones and huge rambles about nothing in particular. Now I "know" her email schedule, if I don't get a replay on Tuesday morning, it means I will get one Thursday night or Friday morning, this knowing of her schedule (she didn't tell me this, I just figured it out based on when I get a replay) stops me from clicking on "check mail" button again and again and again.
