Make eye contact.
Try to maintain eye contact as long as possible throughout your conversation. If a boy maintains eye contact with you, he may be interested in you.
Listen to the tone of his voice.
A change in the tone of voice is a commonality among boys during flirting. Their voice may crack, become higher, lower or even louder. Agree with something he says and listen for a change in tone.
Observe his body language.
If a boy is interested in you, he may change his stance or try to get as close to you as possible. He may fidget and appear to have the inability to stay still. Comment on his body language and observe his response.
Watch for playful touches.
If a boy touches you throughout a conversation, he may be flirting with you.
Make subtle hints that show that you are interested in him.
Observe whether he pursues your compliments or backs away from them.
Ask him if he would like to do something at a later time.
If he agrees, then he may have an interest in you.
- A boy may not be flirting, but could be nervous. Before making a move, observe him long enough and ask questions to determine if he's really into you.
