Update- She didn't even know I was off. My colleague said she went to give me a gift from her sons and was rude to her when said colleague told her I was away for the week. I then got a text from her saying 'Didnt realise you weren't in, when are you back?" Seems all put out that I didn't tell her my plans. She was the only one in the company who didn't know I was away.
