Cabbie21 I had a friend whose son was just a layabout from about 15 onwards, despite being very able academically, he did badly at A and O levels, wouldn't work, ended up with a drink driving conviction and fathered a child at 20.
At 25 he suddenly grew up. Sorted out his life, went to university and got a good degree and has a good job, He married and has two children, but, his one saving grace, was that he always kept in contact with his daughter and paid maintenance, so that now the daughter is grown up and he is a grandfather, they are close.
He is also a loving carer for his father who is in a care home with dementia. When I visited his father, he and his late wife were very dear friends, they cannot sing his son's praises too high.
So there is hope, please believe me, I have gone from being so glad this man was not my son to be proud to call him my son, if he was.
