I prefer chatting and surfing the Internet because you can communicate and share videos, pictures or interesting websites with your friends wherever you are. You also can spend your time watching informative or funny videos, learn some things like foreing languages and other, playing videogames online with your friends. You can also find some new friends if you are too shy to make friends with strangers on the street
