No way to really tell. Of course there are obvious signs, but just do what your heart tells you...
if he looks at you with a smile on his face...
Yes, if you dont know this person.
This could be a sign that the guy is truly interested in you, he doesn't know how to say it. You can pull him to the side and let him know that you don't like it when he makes fun of you.
it means they are not interested
Maybe he doesn't know that you are interested in him.
Maybe he is waiting for you to make the first move. It could be that so that he will know if your are interested in him too if you do make the move.
The guy is often giving you looks, he starts conversations with you or whenever you see him he can't stop looking, or he smiles at you. These are some of the basic ones. But be careful, he could just be really nice.
Answer No. It means he likes you, he is interested and wants to get to know you better.
If a guy is truly in love, then will know by the way he looks at her, acts with her and talks about her when she is not there.
That he wants to "get to know you better."
We don't really know what kind of guy she is interested in since she hasn't talked about that before.
Just about like that. Just tell him you know he is interested in you, but you are not interested. Thanks, but no thanks.
