Hi, Dave.
Tony, I'd like you to meet Professor Smith. Mr. Smith, this is my friend, Tony.
It's a pleasure to meet you, Mr. Smith.
Nice to meet you, Tony.
Dave told me how much he enjoys your class.
Did you, Dave? Well, Dave helps to make it a good class.
Oh, that's interesting. Excuse us, we're going to catch a movie, and it's about that time. Very nice meeting you, Professor Smith.
Same here. Have fun!
