My family

There is are five people in my family. My parents, my grandmother, my brother, and me I. But we stay unhappy. Because of my grandmother, my parents often hate each other (my parents often argue a lot). My father won't use money on my mother (My father won't spend any money on my mother). Although My family is not poor, but I would rather have a happy family than ruch rich one.

In the second sentence, one should say "I" instead of "me" because "parents", "grandmother", "brother", and "I" are the subjects of the sentence. You would use "me" when you are the object of the sentence, as in "He gave me five dollars."

Great job overall! :)
