Pick a good time: Wait until your parents are relaxed and have some free time.
Be direct: Say that you want to talk to them about something important.
Express your feelings: Explain that you're interested in dating a boy and you would like their support.
Be honest: Tell them about the boy you're interested in and how you feel about him.
Listen to their concerns: Let them share their thoughts and feelings; they may have valid concerns to think about.
Respect their decision: Remember that your parents love you and have your best interests at heart. If they don't allow you to date right now, respect their decision, and know that there will be plenty of opportunities to start dating in the future.
Remember, at 11 you have plenty of time to explore relationships and dating. It's essential to get your parent's permission and involve them in your decisions during your childhood and adolescent years!
