I have to say I think this is harsh. Death takes people funny ways.And as a bereaved relative, you don't (or I didn't) actually always know what you need until it's given).
For example, I was all set to clear my mum's house by myself, no fuss etc. My best friend knew how much I hate driving (mum lived a long way from me) and said "nope, I'm going to drive you there, I'll help as much or as little as you want, if you need me to I'll just drop you off and go away until you need me to come back, or I'll come in and help, whatever you need but you're not driving there all by yourself".
I'm sure you'd have found her insistence really presumptuous, maybe intrusive. And I did protest because it was such a massive undertaking for her and I didn't want such a fuss made of me. But it turned out to be just what I needed. She helped me to make difficult choices about things of my mum's to keep and get rid of, did the boring jobs like going through the post while I sat around in the attic crying over old ornaments, made me laugh when it was all getting a bit dire. She was amazing.
And yes she's a bit of a storyteller, and I imagine this is one of her stories she tells about herself. But that doesn't do me any harm.
People trying to act 'the most bereaved' when they barely knew the deceased is a bit crass. And the story about the idiot trying to muscle in on the pall-bearing is just sick. But people offer support the best way they know how; it might not always land right, but I think reading malign intent into it doesn't help anybody.
This reminds me of the thread this weekend about someone sending chocolates instead of flowers to their bereaved friend; so many people saying they'd take it really badly, chocolates are for celebrations etc. Who, when bereaved, has the headspace to be imagining offense when none was clearly intended?
