I had a job interview this morning. I called her afterwards and she said I probably wouldn't get it as there was loads of applicants 
I did get it.
So I called her and told her the good news. Her reply was:
"oh, well to be honest do you not think it's a bit unfair on all the other applicants?"
I said "how??"
So she said "well, last time we spoke about it you were unsure if you even wanted it or not. That job could have gone to someone who really wanted it".
I did "really" want it!! I was just nervous about giving up my current job!! but that's so like her, to piss on my parade, to be more worried about everyone else and to make it obvious that she was hoping I'd fail.
Only rationale for it is that my younger sister is struggling to find work at the moment so is relying on agency work. But I went to university for 4 years, I worked voluntarily, I did all sorts to get where i am and we're both her daughters so why wish one would fail??? I don't get it.
