And, although a boy may have given you a letter in junior high to tell you he liked you, that's unlikely to happen these days (though it's an interesting technique!). Whatever has brought you to this point in your life, you've had enough to deal with. You're probably not going to get another note passed to you from a boy. The good news is that many people don't need notes passed on them. They can tell by the way someone acts. By what they say and how they say it. And most of all, by their actions. If someone is nice to you, shows interest in you, gives you advice, helps you out when you need it, then you should be saying "thank you" and "I like you too!" even if no note was passed. So, yes, a boy can pass you a note to tell you he likes you. Just like any other boy, he will want something in return. But it could also be as simple as writing "I like you" on an envelope and putting it in your mailbox. Or buying you a box of candy or flowers. There are so many ways boys show their feelings these days! The important thing is that you know what you're feeling toward each other. And that you both are comfortable with how things are between you.
