There are different levels of bad decisions people make in life. On the one hand, you have the small stuff, like taking the wrong freeway home from work, or eating gas-station sushi. And on the other, the monumentally awful decisions: ignoring the IRS; signing A-Rod to a three-year/$61mil deal right before he turns 40; and, yes, trying to forge a relationship with someone you meet on vacation.
The problem is, of course, that A-Rod's also coming off a one-year... sorry, wrong example. The problem is that movies about vacation flings that fall apart the week after everyone gets home don’t really sell tickets. But fairytales about love-at-first-sight do.
