I had to write an email to the headmaster. I wrote 'Dear Mr xxxx' and signed my full name. He replied to me 'Dear (my first name) and signed his first name. Should I take it as an invitation to call him by his first name or should I stick to the initial form I used which will be 'Mr xxxx'?
He didn't say, 'call me (his first name)' so I feel it's a bit too cheeky of me to jump into following his suit. I wouldn't like to sound too cold, but I would like to sound as polite as possible. We are discussing some issues at school.
I need to write a reply soon. Can anyone give me advice, please? I really appreciated it.
