I can feel love, admiration, and respect in what is written. I am sure your nephew and nieces will be glad to have you too. You may not have any kids of yours for reasons known to you, but you do have lots of them surround you as I am a kid, too, and I am here loving every piece you write.
I played football and was also a goalkeeper until the injury I got, which said goodbye to my football life. Hehe. And I did other sports too, but I didn't go deeply into them.
