My regret and hope

I regret as I sit having a latte on a Sunday morning watching groupings of people interact. My child who is 32, missed his teen years with me out of choice on his part. I regret this. In spite that I had no choice I perhaps blame myself to some degree.
My hope is when and if he chose to walk back into my life I may see a glimpse of what I missed as well, those teen years. Uh
