Dear Leo,
Thanks for your letter.
You told me that you did not know how to get along with your parents in the letter.Here are some suggestions from me.
First,you should respect them.They are your parents.Even if they don't do the right things sometimes,you should not shout at them.You can stay quietly and talk to them later about it.
Second,you should tell them that you love them.They have emotions.They would be happy if you tell them you love them.
Last but not least,talk to them often.You are a family.You should listen their ideas and tell them what you think.Communication is important.
Hope this can help you.
Yours sincerely,
Tim
