Unit 3:

- I don't have a standard music hobby, I can easily remember the melody, sounds of a song. I'm not so into K-pop like girls at my age, I kinda prefer pop and rock more since Imma boy.

- Music does affect not a little part to me. Of course because it makes me relax, but besides I like the lyrics too. Some lyrics means a lot, we are even able to learn some life motto in songs, which is perfect.

- All Vietnamese singers are my favorite.

Unit 4:

- The biggest benefit is saving the environment and help the homeless. When we ended up use something, such as clothes, throwing it away will be a waste. Maybe the clothes are still useful, or its material still in good condition. There's always someone needing clothes.

On the other side, bottles. Plastic bottle cause the worst consequences to the environment, you've may already known that. How about glass ones? A production of a glass bottle isn't quick and easy, it takes time. So why don't we save that time cleaning and giving to other people?

Sometimes what seems useless to you is what somebody wish to have.

- No absolutely not. Take the flooding disaster in Central as an example. No water, no food, no clothes, no nescessary tools. What can money help? We cannot just easily buy the products. Remember, there are no transportation or pre-cooked food. So money to me is a little useless in this case.

- Support each other.
