I think it got confusing in the other thread, as to what people were actually talking about or responding to. You know, sometimes they dont read thru the whole thread, they just read the last couple of posts then chime in.
And hey quit calling people over a certain age bad names! Like "grandfatherly"!

We still think of ourselves as young - we forget we have white hair and wrinkles - WE can't see them, we're looking at YOU!
Really, I think your new old friend was just showing that he was still "with" you, that he was there for you, in spite of your being ill, rather than that he was ignoring your being ill for his personal gain. I think you are not used to having someone comfort you at such times? At his age, he is probably more used to being around someone ill.
