Dear Mom and Dad,

I’m having a good time in Taiwan.  Last night, we went to KTV for the first time. ______ I wasn’t sure what to expect, I was kind of nervous.

I could not understand why people would find singing along to songs any fun.  I enjoy ______along to the radio at home, but I could not understand why people would pay to sing in front of dozens of other people!

At the KTV place, we paid for our own room with a TV and two microphones.  We looked through a large book with all the songs we could choose to sing.  Most of the songs were in Chinese, so I couldn’t understand them, but ______some English songs that I knew.  Once I started to sing, I had a lot of fun, and it was funny _____my friends sing.  I can’t wait to go to KTV again!

Love,

Daniel
