At age 14, my son did. After a particular egregious offense from his NPD father, we went to court and took away his custodial rights. After that, DS blocked him entirely on his phone, social media, etc. and didn't respond to him for 2 1/2 years. Since then, he acquiesced to one 1 hour lunch visit and then decided he still doesn't want contact. I don't know how this impacted his father's other children, but they are adults at this point.
ETA: Oh and DS never had to 'realize' he was his father's golden child - he literally referred to him that way. Disgusting.
