Have you ever felt like what you were doing was pointless?

Today was one of those days. I'm sitting in class, and realising that all I'm hearing is "blah, blah, blah..." This is the most useless and pointless class I've ever had to sit through. The instructor keeps drilling the same useless information into our heads.... and then I remember exactly how much I'm paying for this waste of time. Honestly, no one in the class is paying any attention to her, and yet she goes on and on, and on like the energizer bunny. The only typing that's going on are those of us who are doing other things like talking on msn, writing emails, writing blogs, working on other assignments... and yet she doesn't notice. I've got 35 minutes of this bull$&^! left. Garrrr! I want to leave NOW!
