Reply To: parents and cell phones

To JosephF-Shabbos may be important as family time, but on Shabbos can my father go bike riding wiht my family? Can he help me with school related stuff? can i talk to him about anything i want? What about the 70 yr old guy that comes over almost every meal? What about when he naps? So cell phones do drive me crazy and even if it is work relateded, do you need to use the phone for 64 (yes 64) minuets? Dont think so.
