Newsflash - it's possible to both travel to and lay flowers on a person's grave/outside their house AND donate to charity at the same time! Now who would have thought that? 
OP, fair enough if that's your decision not to go. I've already mentioned that I make a biannual pilgrimage to the grave of my favourite singer on his birthday and anniversary, where I leave a card and flowers. I don't just "dump" my "£5 Asda carnations"
(although why the fuck it should matter where flowers were bought, or how much they cost, is beyond me). I arrange them carefully in the vases and pots, and tidy up and clean the headstone if necessary. I don't have a photo taken of myself, weeping and wailing (I don't think so), or otherwise.
I do take photos of the flowers and post them on a closed, private FB group which is accessed by fans as well as several close family members and friends of this singer. I also often take pictures of the surrounding area, as his grave is in a lovely spot, overlooking the river, and post those pictures too. Some fans live overseas and are unlikely to be able to visit, so I know they appreciate this.
I've mentioned that sometimes I've met family members on some of my visits. We have a little chat before going on our way. They appreciate the tributes and love that are still shown towards their relative, and have never had a problem with fans quietly and respectfully paying tribute.
Oh, and I have a regular DD set up to donate to several charities, including one that is particularly relevant to this person. I'm not making a big thing of that, but since some on here mention charity. After all, I hope that nobody disapproving ever spends money on treats, meals out, trips to the hairdresser, salon etc. Because yunno, you should just donate that money to charity instead. 
Anyway, I already have arrangements in place for my next visit (it's a major anniversary), and I shall give not a fraction of a shiny shite whether or not any of the espousers of some of the nasty, snotty, sanctimonious tripe on here approve.
And I make no apologies for my overuse of
in this post, either.
