Five reasons not to go home right before a final:

1) Your father might reveal that he was recently diagnosed with Type II diabetes, and could have all kinds of negative health problems or die if he eats too many sweets. Then he could down an entire box of several dozen chocolate eggs left over from Easter in front of you.

2) Your father could spend a large part of the evening talking about how he expects to die soon, and planning how the family could get along without him.

3) Your parents might tell you that your favorite (and only) uncle's cancer means that he might, in fact, only have weeks to live instead of the months or years you expected.

4) You might take the opportunity to do your laundry only to realize upon removing a load from the dryer that you left an ink pen in one of your pockets and most of your clothes are ruined.

5) Your brother might call and reveal that he expects you (so penniless that you had to borrow money from your parents to pay for the plane ticket out to his wedding) to pay for your own tuxedo rental in his wedding, necessitating even more scrimping and saving, and then go on to reveal that he needs tuxedo measurements in the next few days (during finals, of course).
