Sharing a bed with another person can reveal aspects of his or her life that would otherwise remain a mystery. It is the best way to find out if someone snores, sleeps with a stuffed koala or cannot control his or her bladder. It is also the only reliable way to determine the compatibility of your cuddling styles. In this article, I will outline the rules of co-ed sleepovers with a new person:

1) Look all around the room for hidden clues.

Does this person have any types of absurd shrines? Have they created an effigy of you upon which they cast spells? Are they hoarding McDonald’s cups on their desk? Do they use a giant tub of protein powder as a doorstop? Be like Sherlock Holmes and piece together any evidence indicating that your crush is a loon. Decide at this point whether you are actually going to take them up on the invitation for a slumber party. I would like to say that most people aren’t nuts, but that would be a lie. It’s best if you can find out early on.

2) Don’t pack an overnight bag.

This makes you look presumptuous and desperate. Remember, you’re sleeping over someone’s place for the first time, not moving in. If you are really concerned about hygiene, just bring a toothbrush with you and steal some of their toothpaste.

3) Don’t sleep for a million hours.

I made this mistake this past weekend. At 1:30 p.m., my crush finally told me to wake up because he had to drive me home. I overheard his roommates talking about people “getting too comfortable” and could only assume they were referring to my lethargy. The lesson I learned from this is to wake up in a timely fashion and don’t loll around while your bed date is going about his or her daily tasks. This makes you look lazy and hung over.

4) Don’t preemptively remove your pants.

Pants are optional. Just know the repercussions of removing them. “You have to know what you want before you take off your pants,” says 7th-semester undecided major and self-proclaimed “woo girl” Erica Zane. Taking off your pants sends a message that you are “DTF.” If that is not the case, then make your intentions clear. Also, don’t “surprise” your bed partner by getting fully nude and hiding under the covers, otherwise known as the “naked man” technique. While funny at times, it’s mostly just crude.

5) Don’t look really awful upon awakening.

If I plan on sleeping in someone else’s bed, I aim to wear less makeup than usual. Skipping the full-frontal smoky eye ensures that I won’t be mistaken for a Ke$ha come daybreak. If you have a ton of eyeliner and eye shadow on before sleeping in a dude’s bed, try really hard to wash it all off before you go to sleep. You will be glad when you wake up. If you are a guy and you don’t wear makeup, you will probably look exactly the same the next day and don’t have to worry about this.
