Oomis: I was pointing out how the parent never tells the kid their age I still have yet to see someone bedavka not telling the age of the kid. How many kids my father (and I try also) is particular “
Whoops, I misread what you posted. The parent who refrains from telling his children how old he is might possibly believe in the Rashi (Toldos)that explains that Yitzchak Avinu started to worry about his mortality when he reached within five years of the age at which his father died. Maybe that parent does not want his kids to start to worry after 120 years when they reach that point within five years of his age at which he is niftar. I am not saying I believe one should not tell their kids their age for such a reason, but I guess there might be people who do feel that way.
