I'm afraid that neither of my parents have taught me much conduct. It just came to my mind that when calling someone on the phone, if you should,
1. begin by introducing yourself like 'Hi, this is me' and then wait for the other person to say 'Oh, hello', and then state your business.
or if you should,
2. introduce yourself and then directly state your business, like 'Hi, this is me, could I speak with that person?".
Which one of these two do you use and why?
