Self-Confident Man Intonation

A video clip from My Blue Heaven, linked at YouTube.

Watch Steve's intonation closely. Although her reactions were given by the script, his voice and body talk say "self-confidence".

Next, you can notice as he did not offer his name, but he rather waited for her to ask. When she has high interest level, she asks personal questions. In the end, he avoided an exploit, when she complimented his name. He put a grade up with a fabricated meaning of his name - he agreed with her, said thanks and made a room for a joke to raise her interest level again.
