It seems like you’ve missed my point utterly. My explanation was targeted at my elderly mom, not at Hacker News readers. Her responses were genuinely hers, and I think they are reasonable given her understanding and my explanation. I apologize this didn’t come across and I’ll have to rethink how I phrase something like this in the future. That said, your response was emotional as well: as if your words were cast down from on high, a gift from the gods! Your arrogance and rudeness should inspire some self-examination, but I am not hopeful on that front.
