First of all... That sounds nothing like the tone of actual someecards. So, strike one.
Second of all, I hate statements like that just in general. Seriously, shut up! Guess what? It's all relative anyways. Your day is still better than someone who is starving to death, dontcha think?
SO, I think I'm still allowed to say my day was bad, even if it was spent having people screaming at me over trivial matters such as coffee, instead of saving lives and having people poop on me.
