Melissa: you know, i've been thinking a lot about where to go to college lately.

dad: of course, you'll want to go to the best school in the state, my alma mater, for your pre-med classes.

melissa: well, my s. a.t. math scores were really low and my art teacher says she is going to exhibit my last drawing in the big art show downtown. i really love to draw and paint. i'm thinking of exploring an art career.

dad: we all struggle with some subjects, but you'll me when you have your medical practice some day.

melissa: dad, my talents and abilities are not the same as yours. i really have a passion for art. i love to express myself in my drawing. this is my most recent drawing. it means a lot to me.

in the above scenario, what is the communication roadblock?
