The Dark Side of the Moon feeling

This morning I had a moment to reflect on how differently I’m able to interact with my two sons, one 15 and the other 13. My oldest son has reached a point in his life where he enjoys conversation. No subject is out of bounds and I think I get as much or more out of the discussions as he does. This is in stark contrast to what my younger son is able to provide at the moment. With him it’s the typical parent-child dialog where the parent has to play 20 questions just to get anything out of the child and there are more moments of silence than moments of verbal exchange. I’m not complaining, I realize this is typical and I had the same experience with my older son when he was that age. I’ve come to consider that age as a “Dark Side of the Moon” period. But it is very frustrating.
