My hobbies are music, mathematics and reading and traveling around the world and learning about different cultures and histories. I can play guitar and harmonica. I am currently learning piano. If there are common interests and hobbies, you are also interested in them. We can be friends and understand each other's situation or help in some situations. (I need to communicate and gain different perspectives on various things. If it is just to accompany you when you are bored, then I will refuse to communicate. Finally, don’t say “hi”)
