She waved and said hi to me recently as we passed each other in the corridor. Maybe I'm reading too much into things but a wave when you are 6 feet away from each other seems like quite a positive sign. I've been deliberately stopping myself from waving at her cause it seems too needy.

When we chat she makes a point of saying she was out with her 'girl' friends or guy who is 'just a friend'. It's like she doesn't want to turn me off her.
