How can you tell if an older guy likes you and you dont see him at school because he live right next door to you and by the way he is two years older then you?

Answer 1

If he smiles at you, and you catch him looking at you when you're not looking at him, he probably likes you.

Answer 2

If the older guy shows consistent interest in you, makes an effort to spend time with you, compliments you, or engages in meaningful conversations, these could be signs that he likes you. However, it's always best to directly communicate with him to understand his feelings and intentions clearly.
