Other people can be really confusing, especially when it comes to crushes and dating. He might stare at you throughout English class then ignore you in the hallway. Maybe you've got a sneaking suspicion that your best friend has the hots for you. How can you tell for sure if he likes you? Here are a few signs that he or she is probably into you.

1. Your gut says "Yes!"
OK, this may be a frustrating piece of advice because, as a teen, you're still learning how to recognize and trust your intuition. However, if you have a feeling that someone's falling for you -- even if you can't put your finger on why -- it's probably true. With time you'll learn how to recognize this feeling better, so don't sweat it.
2. He can't take their eyes off you
Like a moth to a flame, he won't be able to avoid staring at you. He may look into your eyes for a long time, or he might glance at you compulsively then look away, but one way or another, his gaze is constantly headed in your direction. This is one example of body language -- a great clue about whether someone likes you.
3. He wants to be near you
If he likes you, she's likely to put himself near you whenever possible. Maybe he finds a way to pass you each afternoon in the hall. He might not say anything to you, but he wants to learn more about you.
4. He remembers things you say
Two weeks ago you mentioned that you've always wanted to learn how to sail, and he brings it up when you're chatting. Maybe he remembers that your favorite color is green or that you're deathly afraid of heights. In any case, if he's paying attention to little details like this, he's probably into you.
5. He thinks you're hilarious -- Even if you totally aren't
You told the worst joke in study hall the other day, and he was the only one who laughed. Maybe you made a pun that caused everyone else to groan, but he held his tongue.
6. He smiles like it's going out of style
When you walk into the room, his face lights up. You raise your hand in class, and he grins like he's just won the lottery. When you talk to each other, he's smiling big and paying attention. Yup, he thinks you're the bee's knees. Now ask him out already!
7. He tells someone he likes you
He might tell one of her friends that he likes you, or he might be a little more subtle and say something like "Wow, Anne is a really great dancer" or "Don't you think Jamie is the nicest girl ever?" In either case, he thinks you're pretty great and would probably be thrilled if you asked him out.
8. He asks for your opinion
He asks what you think about something that's important to him, whether it's his blog or his new pair of sunglasses. He wants to know your take on global warming or your predictions about which team is going to win the Super Bowl. He's probably pretty keen on you, and this is a great opportunity to strike up a conversation -- and maybe more.
