<human>: Can you provide a brief overview of the text?

My brother and I had an age gap of 10 years, so growing up, we were more like two only children than siblings. When my brother was younger, I was more of a third parent to him than a sister. We never got into arguments, and he basically listened to what I said. The fact that we are opposite genders also contributed to that. However, I do miss the perks of having a sibling that I can argue with and relate to. At this point, I'm married and thinking about having children, and he is in his senior year of high school. I want to be able to relate to him, have him confide in me and open up to me about what's going on in his life. He's fairly introverted and closed off with our family members but very talkative and outgoing with his friends (typical teenager). Do I just need to wait until he is older and we are in a more similar stage in life before I will be able to relate to him and get close with him? Is there anything I can be doing now to foster a more intimate relationship with him?
<bot>: I want to bond with my younger brother, but don't know if I just need to wait or if I can do something now to foster that relationship.
