I like D of C's cartoon .LOL
I dunno about singing while you drive , lots do (on an open straight road ) Do they really think driving a family to a meeting is a calm happy affair? In my experience it was rushed, late , tense , after getting washed & changed and ready.
However, my beef and that of the dub family members was " How can you remember the words of the scriptures or the songs when the keep changing it ?"
My Missus gets puzzled looks and patronizing corrections if she refers to Bible verse from memory......they have changed the words now in the revised NWT . The old songs too now have different words......That is counter productive to remembering it.
