M：Hey, Alice, my friends(19)just invited me to go to "ka la okay" with them. Would you like to come along?
W：Where are you going? California? Do you mean karaoke? We pronounce it "carry oh key" in English, with the emphasis on the "oh".
M：Oh, I see. Do you want to go to karaoke with us? It’ll be fun!
W：(20)I feel nervous when someone hands me a microphone. I freeze. I know I’m not a very good singer.
M：That’s strange! I thought Americans were very outgoing.
W：Not me! I’m very shy, especially in front of a group of strangers.
M：Hey, my friends aren’t strange!
W：Sure, they are not strange. They are normal. "Strangers" just means "people I don’t know". It doesn’t mean they are strange! Was it easy for you to sing the first time you went to karaoke?
M：For me it was very easy, I love to sing! But now that you mention it, some of my friends were very shy the first time they went, (21)One of my friends says he has to have some beer before he can sing in front of people. Maybe you should have one or two drinks before singing.
W：Really? One or two beers might help? Well, I may need a dozen of beer.
M：Don’t be shy. Just join us. (22)You may first make a song list and practice singing at home before hand.
M：It sounds good. But when will you go?
W：On Friday evening. So you’ll come, Ok? W：Okay, I’ll give it a try.
