Scott doesn't talk much, but five girls in our homeroom class are currently competing for his attention. This is nothing new. Girls have liked Scott for as long as I can remember.
Suggested Answer
Irritable, harsh, inconsiderate
Answer Explanation
Pete seems to be overreacting to a pretty fair request by Mark. This shows that he is irritable and harsh. Perhaps he is also inconsiderate, because he doesn't think about Mark's situation or why he might only have brought one pencil.
