“What is one thing in your home you couldn't live without? Why?”

I couldn't live without my laptop, because I use it for work and entertainment. I don't have a TV in my small studio, so that I always use my laptop.
At home, I do research and write reports on it, and I also watch TV shows or enjoy music as a hobby. These days, many online and meetings are held in online, so I can not do anything at all. Sometimes I even think about a bigger Macbook laptop
