when you reach age 40, will have families to look after and a lot more to lose than they used to have, like a nice house and a good job
or they'll be at the far end of a skype link / international flight
or they'll have discovered a new chill side to themselves now they don't have 19-year-old energy and hormone levels
and you'll realise you don't want your boy to fuck up his custody arrangements by getting sent to jail over some dumb brawl
They'll still support you in the face of life's challenges, but it'll be support of a very different kind.
