I hate when people have first names as their last names. It make's it confusing when responding to email. For example is Joseph, Donald a Donald or a Joseph?
You illiterate piece of poo. Nobody goes by Firstname, Lastname. If they have a comma it's to denote Lastname, Firstname. Donald Joseph, or DonJo. More importantly, why does it matter? You should literally care less.
It seems to me that this latest generation coming to age has their own opinion on formal dress attire. When I was much younger people always wore suits to weddings and funerals. I suppose it was a sign of respect. I still dress up for both. I believe in the right circumstances it's acceptable to go casual to these events especially if you don't have formal clothes. After all, just showing up means you care. However these days I think many people don't care and just show up in whatever the hell they feel like.
I'm pretty sure it's a hipster thing, and that they're either trying to be ironic or show how apathetic they are. Hipsters make me feel like an angry old man. They're from the generation after me, and everything they do annoys the fuck out of me.
