Left-handedness and KTV

Almost every Chinese person that I written or eaten in front of has noticed that I am left handed. They always tell me that in China, left handed people are considered smart. But, they also then tell me that I should write my characters and use chopsticks with my right hand. Apparently Chinese left handed people must learn how to use chopsticks, write characters, or do calligraphy with their right hand. After taking my calligraphy class last semester, I can definitely see the advantage of being right handed (all the strokes have angles that are not only advantageous to right handed people but rather uncomfortable for left handed people). I am surprised by the large number of people that have noticed this and called me out on it, suggesting that (while/since) I am "smart," I should learn to use my right hand to use chopsticks and write...

Tonight we went to a very popular weekend activity for a lot of Chinese people, both young and old: KTV. We rented our own room, complete with couch, tv, and kareoke equipment and sang our hearts away for the next (almost) 4 hours. The KTV place we were at was so full we had to wait 1/2 hour to get a room. When we finally left at about 2:15, there were many rooms still full of people singing and having fun. While it was definitely a fun night, with a few Chinglish translations of English songs, I wonder what about the activity is so incredibly attractive. We went to the cheapest one in the area, and with 8 people, it was about the price of a medium priced cover charge for a bar in Beijing. In some respects, if you compare it to other entertainment options, the price is not an issue. The group gets its own room and can eat and drink and be merry until the wee hours of the morning (our room was rented until 7:00 am). However, what about singing kareoke is so amazing that a KTV bar on every major corner can stay busy and attract such a large age range?

On one hand, pessimistically speaking, I might not want to be holed up in a room with 7 of my close friends singing off tune kareoke for hours. However, the Chinese people that came with us were really good singers so maybe that is not an issue here.

On the other hand, maybe Chinese people just like to sing! Perhaps it provides a way for families and friends to get together: they don't have to worry about it being crowded and noisy (like a bar), it's kid friendly (unlike a bar), and they get to spend some quality time together (unlike a movie or show) while also enjoying a fun activity. Also, while in the US we would probably just invite our friends over to our house and buy or rent a kareoke machine, here, the average house/flat is too small to host a large group of people and transportation to people's houses are more of an issue, so getting a big group together in a comfortable situation can be unrealistic, but not at KTV!

*Edit* I asked my roommate why they love going to KTV and she basically gave the exact same reasons as the ones I mentioned above. She said they like to go because they get their own room and they can chat and hangout. Their houses are too far away and too small to have a lot of people over. She said Chinese people also don't like making food for a large group of people, so they can go to KTV, eat, hangout, and then sing kareoke. Even if they can't sing very well, they still like going. She also said in high school they would go there a lot after lunchtime!
