My family members

I'll introduce my family members, especially my brother and sister. Each of them (is a completely different kind of person/has a completely different personality).
First, my brother (is a person/is the kind of person) who often goes out if he has a free time. He likes to (play/hang out) with his friends after university classes. In On holidays, he tends to disappear from our house because he usually (visits somewhere out by bike/goes out somewhere on his bike). There are many cases where he goes out before I get up in the morning. He also likes singing songs. When he feels really good, he sings in a loud voice. Truly, he is an active man.

Second, my sister is (a person/the kind of person) who likes reading and watching TV. She prefers to staying home even when it is a sunny day. She recommends that I should read more novels, though I don't have enough time to read such long books.

I wish I could see them more..
