Whats the point of coming to school ?

Well i got a so-called-friend in my class, everytime she comes to school, she is either sleep or copy answers from other people.Thats what she do and PMR is coming yet she doesnt wanna study hard for good results. Many friends of hers already advised her to study hard, but she keeps on scolding them who advised her. Whats the point of coming to school and waste her parent's money ? Why dont she just go work or go to fufill her dreams that she always wanted to ? Well i dont know whats her future but i hope she might wanna study =)
