Dear Diary,
Big argument with my parents tonight. I told them
I want to attend a march next weekend to suppor t the
environment, and what did they say? Did they say,
“Good for you, Beth”? Did they say, “Great idea! We’re
really proud of you”? No way. Mom said: “A march? But
marches are dan gerous, aren’t they?” And Dad said,
“You’re kind of young for marches, aren’t you?” “Dad,”
I said, “I’m 16. I’m not a child. I can look af ter myself.”
Dad said, “I know you’re 16. That makes you a teenager,
doesn’t it? Not an adult!” And he and Mom started
laughing.
So I stood up and said, “L ook. You’ve heard about global
warming, haven’t you? Well, it’s happening now. And
this is a problem! I’m trying to do something. OK? So I’ll
be at tending the march on Saturday.” Then I stood up
and walk ed out of the room. I can’t believe them! I don’t
understand why they won’t suppor t me when I’m trying
to do something good!
Now I’m sitting here in my bedroom. I can hear voices
downstairs. Maybe it’s the T V, but actually I think it’s
my parent s arguing. That’s strange. They don’t usually
argue. Well, not with each other, only with me, of course

Questions:
1) What is the march next weekend about?
2) What did Beth want her parents to say?
3) What reason does Beth give for wanting to go on the march?
4) Why does Beth think it is strange that her parents are arguing?
