It's Friday, so Happy Friday, I guess. My co-workers can wish each other Happy Friday all they want, but I find it rather redundant. It's Friday, of course it's happy. We are a culture that jumps at the chance to shirk responsibility, and what better day than Friday to do that? For a genuine greeting, consider Happy Birthday--usually not redundant, since somewhere in your 20s you stop being so happy about your birthdays. No heaps of presents with your name on them. No superheroes appear at your birthday parties. I tried to get one to come to my 24th birthday party (bar undisclosed), but he was turned away at the door, and I was called a pervert. Everyone's so critical.
