1. Expectation: "He can give me guy advice!"

Reality: Most of the time when you ask your guy BFF for guy advice, he will shrug and continue eating Fritos. Guys don't have any more knowledge about how some dude he's never met operates any more than we do. If I asked you what some girl in your office is like on a date, could you tell me? OK, so maybe you could but also you're very smart.

2. Expectation: "I'll hang out with him and his friend, and I'll be one of the guys!"

Reality: I wish this were a thing, but truthfully you will probably just be his friend that everyone wants to sleep with. Guys often have a really hard time differentiating "cool girl" from "girl I wanna sleep with." And just because you're his BFF doesn't mean you'll be seen as a sexless bro.

3. Expectation: "I'll always have a date!"

Reality: Only if he's single and chronically unemployed. Otherwise he probably has a life and/or is super lazy and will not want to go with you to your Jewish singles mixer.

4. Expectation: "I'll understand men more in general!"

Reality: If anything, it's possible you'll actually become more confused, because the more time you spend with him, the more you'll realize that even if he is a guy, he's also a person and people are complex and no one makes sense 100 percent of the time. Plus, even if you do figure him out, the guys you're going for probably won't react the same way the same way he does every single time, so you're back to square one.

5. Expectation: "Being BFF with a guy will be zero drama!"

Reality: The myth that "being friends with girls always leads to drama" is lame. Guys get moody and weird and jealous and competitive and selfish just as much as women do. It's just likely to be over something less "Were you flirting with my crush?" and more "You think Channing Tatum is hotter than me?" Um, yes. Channing Tatum is hotter than all people.

6. Expectation: "He can build stuff for me!"

Reality: Have you seen the average guy try to put together an IKEA dresser? That shit does not go smoothly. You basically have to be a ninja with tools your construction worker father gave you to be able to do that and do it well. Plus, there's a super good chance he has no interest in doing that for you, no matter how much he loves you, because everyone hates putting stuff together because it is the worst.

7. Expectation: "Maybe we could be friends with benefits!"

Reality: While that's possible, that's gonna get real weird, real fast. Plus, there's a possibility he is really bad in bed and then things are a completely different kind of awkward between you. Skip.

8. Expectation: "Maybe we'll fall in love some day!"

Reality: Have I had this hope with certain guy BFFs in the past? For sure. But let me tell you, that stuff happens on its own. And even if you do end up together five years down the road, it's not happening now because he sleeps on milk crates with a sheet draped over them, so why not live in the present? The present wherein he is undateable, but also your bestest best friend ever.
