I can never claim I'm a master of sarcasm. I tend to accept things at face value unless someone says something that's completely out of character or nonsense. I can't help it that's just the way I am. Over time as I learn a person's personality I tend to anticipate sarcastic remarks. It takes me a while to pick up on tone of voice, and body language associated with sarcasm because each person's presentation is unique. Frankly I don't know how most people read sarcasm. I'm not demented and I tend to think of myself as being reasonably smart, so I tend to believe mastering sarcasm is not universal human trait so measuring dementia based on lack of perception of sarcasm cannot be that accurate. I will say that my inability to read sarcasm, among other things, causes many of my friends and colleagues to claim that I seem to have Asperger's syndrome but I haven't been diagnosed with it by a physician.

Actually I am a math major (near top of my class if that even matters), and no my math is not wrong...I pay tuition per semester, not per year, and each semester is four months long.

but I'd rather have universities host a music service for their students. I live in Canada so I'm immune to the RIAA (for now, the equivalent Canadian entity make come to bite us soon enough), but I wouldn't mind an extra $100 fee on top of tuition for unlimited access to legal 256kbps+ DRM free music. That comes out to be $25/month, which is less than what I pay for music per month anyway.
