Here's What I Don't Get

I don't get people who go to law school and then don't take the bar exam. I know that the boys over at Barely Legal have some sort of logical explanation for this, but I just don't get it.

First, if you realize after 2 years that you don't really want to be a lawyer after all, then why not drop out immediately and reduce your crushing load of student loan debt to 2/3-of-a-crushing-load of loan debt? Then you'll only have to spend 15 years living in your parents' basement instead of 20 years while you pay off the debt.

And if you do decide to go ahead and serve out your 3-year law school sentence and graduate, but not get a job as a lawyer, still, why not just take 2 more fucking months and study for the bar exam, so that when your brother gets a DUI or your cousin gets ripped off by his landlord, you can do a little bit of research and give them some advice without worrying that someone will catch you doing some "unauthorized practice of law" or whatever it's called?
