i had a situation like this but it was in her office.i was waiting to pay her secitary and someone was infront of me and kind of having a problem with appointments so it was taking a bit but it was ok because i was early.my T came down stairs and was walking down the hall towards me and the other person i smiled and waved and she totally ignored me and just said excuse me as she walked bye me.i was likewhat did i do?i guess im not supose to acknowledge her in the hall or something.i felt like i did something wrong.it wasnt like she was with a client or something she was just bringing paperwork downstairs.it was strange.i know i wont ever talk to out in the hall again
