Greetings, brandnew:
Good for you, helping your dad.
I can see any adult child driving Mom and Dad wherever they need to go, even church. The loving child doesn't have to attend or believe. Ray Franz, in IN SEARCH OF CHRISTIAN FREEDOM, praised a disfellowshipped woman for regularly driving an elderly relative (aunt, I believe) to meetings.
BTW, while still attending the KH, I regularly answered, encouraged by one elder in particular. This, despite hair down my back and a beard. Guess there's more to all this outward appearance thing than meets the eye. Baptized 50 years . . .
Best regards to you and your family.
