His son doesn't understand what troubles is for the dad. I pity
the dad. He should think more for himself and the son.
If he dropped dead who is going to take care of the son? Or
personal glorification?
Sometimes one have to say "no" love or not.
the son already can take care of himself. he's already living in
his own apartment and grad from uni. the dad show his love to him
by this way.
the son also show to others that it does not matter whether are
you disabled, but there is sumthing you definitely can do. The dad
too has become an inspiration to others.
you may think that it's troubling the dad to do the things that
he does but then the dad might not think that way. i
guess.
