Hearing aids serviced and best possible operating condition: check
Dad wearing both hearing aids: negative. He was wearing only one
Dad is a reasonably good mood: negative. He was cranky about the sore on his face, aggravated by "the way the girls on for the weekend shave me" and his burned out light bulb with no replacement in sight.
Dad and daughter visiting alone: negative. Laura wanted to go with me to visit her grandfather. "There's nothing else to do and going will distract me". (sigh)
One out of four requisites didn't cut it. Tomorrow may be a better day to let him know our news and be open to his response. I have no clue what he'll say but whatever it is, he'll (probably and hopefully) be honest and say what's on his heart even though he respects privacy (see last post).
