I remember something similar to this when my mom died 15 years ago. Lots of aunt's and friends reaching out to my sister to support her, traveling across the country to visit. I don't think I ever even got a note.

But I do have the thing where I probably wouldn't have cared either, if not for watching the support my sister got, it never would have occurred to me someone could do those things. And I know those people aren't my actual friends, so I really had zero expectations from them. I think it was more the insult on top of injury that bothered me. "Not only do we not care, but we're going to show you what we would be doing if we did care."

I never took this as a boy/girl thing though. I never fit in in life, still to this day. Just sorta expected.
