Why do decorators usually advise against choosing a fully open western-style kitchen? What is the reason?

A few years ago, due to work adjustment, I needed to move. There happened to be a real estate sale near my new job. Finally, after research, I bought a new house there. The process went very smoothly, and finally I delivered the house as scheduled. It's a little over 100, so it's more comfortable to live in a small room. The next problem is decoration. Fortunately, I have a friend who is engaged in the decoration industry, so I went.

My friends gave me a lot of advice, which I think is also very reasonable. Later, my wife proposed to decorate the open kitchen, because she liked it very much and thought it would be spacious and make the home feel more upscale. However, my friend raised an objection. He said that our apartment, including the structure of our home, combined with his understanding of us, said that our home is really not suitable for building an open kitchen. Finally, we adopted the advice of our friends and redecorated the general kitchen.

Later, we moved in and we got along well with our neighbors. One day, our neighbors invited us to their home for dinner. As soon as we entered the door, my wife and I were attracted by their open kitchen. The kitchen and the living room are integrated, and they have some unique beauty. And because it is open, the space is particularly large. The whole living room seems to have doubled, and the light is very good, which makes us envious. At that time, we regretted not decorating the open kitchen. Later, neighbors can chat with us when cooking, which is also very good. Chatting while cooking also saved the boredom of the cooks, which made us feel that the open kitchen was really great and even redecorated, but later it was too troublesome, so we made do with it.

About half a year later, we went to our neighbor's house for dinner again. This time, we went in and found that the open kitchen was not so beautiful. First, the problem of oil smoke is so serious that even wall covering in the living room smells of oil smoke. Then, because it is an open kitchen, the kitchen utensils and tableware in the kitchen are placed in a mess, which directly affects the feeling of the whole living room and looks messy. It seems that this open kitchen is not so easy to take care of. Then the neighbor told us something. Once he was cooking in the kitchen, his cat suddenly climbed next to him. As soon as he turned around, he was startled and hot oil spilled on the cat. Fortunately, it didn't cause much harm, otherwise it would be too late to regret it. In this way, the open kitchen is not so good.
