Income gives stability and comfort, which help people to be happy and stay calm.

I am learning about [cross cultural<-- I'm not sure what this means] and Japanese culture at university. I also study Spanish, but it's difficult to pronounce. I want to be able to hold everyday conversations!! My college cafeteria is delicious, but I feel it is a little expensive.

I was watching Malcolm in the Middle and it's really funny. It's one of my favorite comedy TV shows. I really enjoy it every time I watch it. Another series that I'm watching is Peaky Blinders, and it's excellent. In fact I watched the whole thing in only one week! It's spectacular.

Short text

Hi,
Please could you correct my text ? thanks in advance :)

One day, my parents were absent out, and I stayed home alone in home waiting for their return. I did many activities such as revising my lessons, reading some books, surfing on the net, and playing in front of home  out front. and I did housework before they came back.

Hi Niwantha, The answer is "it depends." In your example sentence, only "household" is correct. "Baking soda can be used as a household cleaner." That is, the cleaner is a thing which cleans a household. (The second sentence is awkward, or refers to cleaning a servant = "a domestic.") However, you could say both "I need to do some household chores" (as in, chores around my household) or "I need to do some domestic chores" (as in, chores in the domestic sphere). When in doubt: household is more likely to be correct. Or, just ask on italki! :)

Butterfly Butterflies

I see three butterfly  butterflies flying in the wilderness. All of them are similar in their appearance. They are red, dotted with black color.

Any correction??

The "their" and the "color" aren't wrong, but they sound confusing. Once you are talking about two colors, you can skip the word "color."  (It is clear from context.) Also, "similar in appearance" is a great phrase you can use in many situations!
