My son, Li Qiang, is a teenager now. He has his own ideas about how to spend his free time. He wants to go on a camping trip with his friends in the mountains. He says it will be a great adventure（冒险）and he can learn a lot from it.
As a mother, I'm a little worried. I think the most important thing is his safety. I'm afraid that something dangerous may happen during the trip, like getting lost or getting hurt. So I don't allow him to go.
My son is very disappointed. He says that parents should trust their kids and let them be free. He thinks it's a good chance for him to be independent（自立的）.
I understand his feelings, but I'm still hesitant（犹豫的）. I know he needs to grow and learn to make his own choices, but I can't stop worrying about him. I hope we can find a way to deal with this problem. Maybe we can plan the trip together and make sure everything is safe. What do you think?
