One reason– they're tired! Not what you thought I'd say? Ha! Read on...When do teens want to talk to their parents? 10:00 pm. That’s right. Just when you are ready to collapse, exhausted, into bed, your teen will knock on your bedroom door with an innocuous question. If you are coherent enough to carry on a conversation, and can stay calm, the best thing you can do is respond with an attitude of “tell me more”. This late hour (late for you, it’s still early for them) is your best time to get them to open up.
