When you go into a friend's home, it is polite to greet other people (relatives/roommates) in the house. Say hello and introduce yourself. A conversation may or may not follow.
Introduce yourself to people you don't know.
Express happiness to meet the other person.
Make small talk.
You can call me...
Thanks for coming.
Thanks for having me.
I've heard so much about you.
It's nice to put a face to a name.
You have a beautiful home.
Listen and read:
A: Hi Mike. I've heard so much about you. Jesse says you love to play guitar.
B: Yes. I bring it everywhere with me.
A: Well, we're glad to finally meet you. Dinner will be ready in about twenty minutes.
B: Is there anything I can do to help?
A: No, everything is pretty much ready. We're just waiting on the roast. I hope you like roast beef.
B: Yes, of course. Jesse tells me you're a fabulous cook.
