My English teacher is very funny. He has really long hair and wears an earring in one ear. He likes to wear purple shirts and orange pants. He also uses all kinds of slang words from the 1970s. When he likes something, he’ll say it’s really “groovy (酷的)”. I think he played the guitar in a rock band when he was younger.
The other day, he walked into class and noticed that there was a new student. He asked him, “Hey, man, what’s happening?” The student was very confused, but we all laughed because we knew that the teacher was just saying hello. “You’re new, aren’t you?” The teacher asked. “Is this the teacher?” he looks strange. Then he explained to all of us, “Sorry. Maybe I’m in the wrong classroom.”
