Say you get an email at work like this:
"My name is Suzie Nguyen. I have just recently joined our Science
Faculty. I will be working for Cameron E-R at Debbie Massey 's old desk.
You might want to call me as
Ms *NEW* Debbie:)"
I suggest replying with "Hi, my name is Harry, but you can call me Floppy."
However, for best results I recommend using this when meeting a new superior.
Superior: (extending hand) How nice to meet you. Harry, isn't it?
Harry (in a jolly English accent): (shaking hand) Yes, but call me 'Floppy'!
Try it today.
I'm orf to meet the new Dean. Or 'Bubbles' as I shall call him.
