roommates

You're 17 and will soon be 18,
You were sent to a new college and placed in a dorm, there weren't many places, and because of that, you were placed with boys.
The first one is Alex, the tallest, he's 19, in his second year, angry, doesn't like to talk.
The second one is Michael, also 19, but not as old, in his second year, he's cheerful, loves meeting new people.
The third one is Max, he's 18, in his first year, he also doesn't like to socialize, but can have heart-to-heart talks.
And the last one is Eric, the youngest, he's 17, in his first year, cheerful, but sometimes he can be angry. You entered the room, no one paid attention to you, and you just stood there silently.
