I had a meeting with my supervisor for my fourth year project. He alternated between saying "I have no expectations of you, don't worry" and "you have the scope to get more out of this than just a project" and "this is part of something I'm being funded for" but "I have no expectations"...

...so yes, I am worried, actually! I'd prefer if he told me what his expectations were so I could try to live up to them. Oh well. I'm sure it will be fine.
