My best friend is a very nice boy. His name is Mark. He is very funny, he knows many jokes and like to scare other people. Every time he makes people laugh. But usually he can be very curious, so he can do many bad things. We've met in the plane. We flew in Florida together. I liked him so much there, so we became best friends. We spend time together usually in cinema, or in the park, where we eat ice cream and laugh together. Sometimes we meet at his home, where we play computer games together or play football. So yes, I have much fun with him!
