You may be able to tell that a person likes you if they look at you for a second and look away or stare at you for countless hours at a time. You can even tell if they give you obvious signs such as giving you a gift or singing you a son. Does the person talk to you very often? That would be a good sign. They may tease you if you are a child or teen. They may become anxious or nervous when they are around you and the may keep talking about you to their friends. If the person gives you notes in class or study hall, that would mean something too. Do they have your number? If they text you often then that will be a sure sign that they want to talk to you. If they call you a lot, that is even better. That means that they want to hear your voice. I hope that my answer has helped and I wish you the best of luck! Have a very merry Christmas!

You will tell someone likes you if he or she constantly keeps on staring at you and is always in your sight without going far. The person may also be very anxious around you and keeps on talking about you with his or her friends.
