Eh you sure about that"hiya how are you" Fine or crap my dad died which is more likely ? Hiya nice weekend? - Yes fine or no my dad died etc - you would not tell people if this happened?
Not sure I understand that post at all, it doesn't seem to form normal sentences, but I'll have a stab...
Posting a thread isn't the same dynamic, and apart from that someones dad is much more personal. Posting a thread is walking ito a room and saying something to everyone - you wouldn't walk into work and say "my dad died, discuss". That's why "RIP these people" or "Amy winehouse dead" threads are essentially just sensationalist "look I've got news you should all look at" posts, that I dislike.
Well it's a pretty normal and standard procedure to inform others when someone fairly famous has died, or when someone known to them has died - no great mystery there imo.
However there will always be small minority of sad inadequates who see it as an opportunity to inform everyone just how little they care, or how much they disliked the person and how glad they are to hear of their death. What motivates these people is a mystery to me. Although I'm hugely satisfied by the fact that I don't understand their train of thoughts.
I don't think it's that normal to be honest. When I saw Winehouse had died I though "shame for her parents" and went on with my life - why the hell would I post it on singletrack? I didn't even mention it to my nearest friend, and in fact found it really odd when I got a text from a friend telling me. I just don't get why anyone would think it a good idea to post on a forum for discussion, I never do - drug addled person or not. I can understand those who post looking for support with a family member who died, but a famous person (that everyone will find out through the news anyway)? Why? And to then have a mini hissy fit when people say things they don't like? Very odd.
