You're always gonna be his kid no matter what the age and parents always do what they have to do to make sure their kids are doing OK.
I'm 45, married 20 yrs, raising a teenage girl and a 10 y.o. boy, I own my own house and my own business, yet my 83 y.o. parents (who live down the road from me) are always asking - how's business? do you need help? How are the wife & kids? and so on. It never stops. . . . And I hope it continues for another 25 years.
