How to Communicate with Our Parents
Hello，everyone，I’d__like__to__share__my__ideas__about__the__topic__of__communicating__with__our__parents．
Parents are the people who love us most，so it’s necessary to keep a good relationship with them.Here are my ideas on how to make it easier to communicate with parents.
First，we should respect and trust our parents.Don’t be rude to them even if they have done something wrong.They have experienced more and always try their best to protect us from dangers.Second，if we often talk with them about our life and experiences，we will know each other better.What’s more，we can often tell our parents how much we love them.If sometimes we don’t agree with our parents’ decisions，we should try to put ourselves into their shoes and we will soon understand them.Remember that what they really want is only the best for us.
Thank you for listening.
