You say you're old enough to stay out late on weekends while they say you have to be home
early. You say you want to see that new film while they say you can't see it. You say you've met
some nice kids and you'd like to go out with them, but they say they'd like to see your friends first.
When you're a teenager, it seems that every time you say "I want to", they will certainly answer "No,
you can't." Also, no part of your life is safe from the "prying eyes" of your parents. 15-year-old Debbie
says, "My dad always wants to know where I am, what time I'm going to be home. Most parents do
that. Do they have to know everything? 1 "
2 When something goes wrong, most parents just don't believe in their children. Without asking
why, they think their kids are wrong. And not many parents would allow their kids to choose for
themselves.
3 But remember that not too long ago you were really a child. Your parents still remember
the childish mistakes you used to make. They want to protect you though you do not want them to
do so. And when something seems to threaten your well-being, they worry.
So, if you want to get more freedom, please try to understand your parents and do not just lie.
4 If you want them to allow you to stay out late, don't just say, "All the other kids can stay out late.
" Tell them as much as you can about what you want to do and where you'll be and why it's important
for you to stay out later ..., they might just say yes.
A. Yes, it is true that your parents sometimes treat you like a small child.
B. No one likes being troubled.
C. They should give us more freedom.
D. Try a more friendly way.
E. Young people further complain that their parents do not respect them.
