If you want it, take it. What's the worst that can happen if you steal? Well, sure, you could get caught and then your mom will have to sleep with the creepiest detective ever to keep you out of trouble, but no big deal. At least you'll stay in style on the cheap.

Meet a strange boy? Let him live in your house. If he's cute, you'll flirt in the shower and then fall in love. Score! There's no way letting someone you've just met move in could go wrong. It's not like he might trash your place, steal all your stuff, or betray you to your worst enemy... Oh, wait, that last one's possible. But he'll be really sorry about it, so that's okay.

Avoid all cars. Don't get in them, don't get near them, just avoid avoid avoid. Yes, it's a little impractical, but when you crash your boyfriend's ride and get run over in the course of a few weeks, it's time to start making use of public transportation. (We’re sure it’s great in Rosewood.)

Follow your heart, no matter what. Even if your one true love is your teacher and your relationship could get him fired, it's still better to pursue your passion than deny your feelings. Look at what happened when Aria (Lucy Hale) tried dating someone else: She wound up with Noel (Brant Daugherty). Sure, he's hot, but he didn't blink twice at blackmail. Clearly going with your gut is the right move — just don't slip up and call your illicit partner by his first name in class.

If you're having a secret affair, keep displays of affection private. And by private, we mean behind-closed-doors. Draw the curtains, secure the lock. A car in the woods is not an adequate hiding spot for your make-out sesh, and driving into the nearest city to go to an art gallery might make you dangerously close to going on a double date with your mom. Keeping a relationship secret is hard work.

Facebook stalking can be good. Screw privacy. Your boyfriend might have a secret ex-fiancee, and it's important to know these things. Prying into your boyfriend's past isn't necessarily a sign of trust, but there are some things a girl's gotta find out. As long as you didn't mean to snoop at first, once you accidentally stumble on something iffy, any further digging you do is completely justified.

Pretty Little Liars is our favorite addictive drama on TV, but we're glad we don't actually live in Rosewood. We prefer less murder, stalking, and general mayhem in our lives. Plus, we have to wonder about what’s in the water in that little Pennsylvania town, because there's something making everyone act crazy. Seriously, we love all four gals and want nothing more than to steal their wardrobes, but some of their choices are questionable at best.

Don't believe us? We've looked back over Season 1 to figure out what life lessons can be learned from Aria and Hanna. Let's just say this advice probably won't help you win friends and influence people...
