Mom and Dad are two of the most important people in your life.You probably see at least one of them every day. If your dad worships（崇拜）the Pittsburgh Stealers,you're likely to grow up being a big fan of that football team.And if your mom loves to read,you just might grow up carrying a book wherever you go,just like she does.

    Here are four ways you can stay.close:and build a strong relationship with your parents.

    ⑴Spent time together.How much time do you spend just enjoying each other's company?

    Instead of playing a computer game or watching TV,maybe you can ask your mom and dad to play with you.Go outside together,try a board game,or read a book out.

    ⑵Share your feelings and ask for help.Your mom or dad might not know that you're having a problem.Tell a parent if you're sad or struggling with something.

    ⑶Show your care. Some families are always kissing, hugging, and saying "I love you". It's important to show that you care for each other. In addition to kisses and hugs, kids and parents show their love by respecting each other, being caring, polite, and thoughtful.

    ⑷Whatever you do, do your best! You, don't have to be perfect, but when you do your best, you make your parents proud. It makes them happy to see how you're turning into such a great kid. Why? Because it lets them know they're doing a good job.
