My trainee

I am being replaced.
I told my boss that I'm leaving for a new job with a higher salary long ago. He soooooo wanted me to stay but said nothing about my salary,neither to improve it nor even just talk about it.

Oh my God, sighing for the first wokring day? I feel so bad for her.
We've been spending the whole morning in the office to get her familiar to things in the procedure and we spent the afternoon out to see some customers and supplier. Everything went well till the third one. We were on the turn to a big street to the office of the third customer and I was running like hell accriss the yellow light with her following. I easily passed the yellow light without being touched by any policeman though he saw me passing but I made a big turn so he was too far away from me to catch. but when I looked back to find t
