Why?

Why does the hottest girl in class, who almost never sits next to you for lectures (because there is always a rare exception to the law of averages ), have to come and sit next to you right on the day of your mid-term? And why does she have to look hotter than usual on that day? And why does she have to forget her watch and ask you "How long before the exam begins?"? And why does she have to start chattering nervously about how she couldnt sleep the last night because there was so much to read? And why does she have to be all "Oh! This is sooooo time-consuming! How are we gonna get this done in 70 minutes??" in her cute voice during the exam that only you can hear because you are sitting next to her? And why does she have to forget her calculator and ask if she can borrow yours? And why does she have to bump your elbow with hers just when you are doing an ultra-tricky calculation? And why does she have to giggle when the professor makes a joke about there being only 5 more minutes left? And why does she have to ask you after, how you did in the exam? And why does she have to get a call and leave just before you could ask her name?

So many questions....no answers...none at all.
