Acknowledge any compliments that come your way:

If you do your hair or makeup differently one day, and the guy notices, that’s a very good sign that he likes you. Most guys won’t notice, and if they do, they won’t say anything unless they’re into you. Anything like, “You look nice today,” “I like that shirt,” or even “Did you do your hair differently today? It looks nice,” are all indicators that he could be interested in you. NOTE: If he’s a good friend of yours, these won’t necessarily be indicators of romantic interest. It could just be him being a good friend. Not all guys are this straightforward about compliments, so don’t be worried if he doesn’t compliment you.

Watch for him noticing ‘masculine things’ on you:

For example, some of your dad’s aftershave rubbed off on you when you hugged him. Your crush may say ‘is that aftershave on you?’ This indicates he thinks it is from another guy (and not your dad!)

If he talks to you on a Social Networking site:

If he chats with you often he may like you. He could also just be talkative and friendly so don’t assume he’s into you for chatting. He may put ‘x’ on the end of everything he says to you. That might not nessaserily mean he likes you. It could just mean that you are good friends. If he says ‘I know something you don’t know.’ This could mean that he likes you and wants you to be guessing and wants you to know and wants to see if you feel the same way. Or it could just mean he knows something you don’t know, eg. A new colour or the fact that he has a new friend or something.
