My hobby isn't dangerous and it is quiet. I have had my hobby for two years.
I started my hobby when my friend told me about it.
For my hobby I use my smartphone and headphones (телефон и наушники). I need my headphones not to disturb people around me. (наушники нужны, чтобы не мешать окружающим)
I usually do my hobby an hour a day. If it is weekend, then I can spend more time on it.
I like my hobby because it helps me to learn new things, to have fun and make new friends.
