I have always believed that there is one person in everyone's life who makes your heart beat faster, makes your emotions fluctuate, and makes your world colorful because of him. When you like someone, you have a special feeling, a feeling that you can't describe in words, that only you can really experience.
Like someone, you will have an urge to get close to him. You will find all kinds of excuses to talk to him, you will pay attention to his every move, and you will care about his preferences and habits. You will reach out when he needs help, and you will be there for him when he feels lonely. You'll even sneak a glance at him when he's not looking, and then smile contentedly.
Then, you will have a desire to get to know him. You'll want to know his story, you'll want to know his dreams, you'll want to know his past and future. You're going to want to know his joys and sorrows, you're going to want to know his thoughts and ideas. You'll even want to know every detail of him because you know it's all part of him and the reason why you like him.
When you like him, you also have an urge to protect him. You will stand up when he is hurting, and you will support him when he is in trouble. You will give him encouragement when he is lost, and you will share it with him when he is happy. You're even going to suffer a little bit for him, because you know, it's a way you like him, it's a way you want to protect him.
In the end, you will have a desire to be with him. You will imagine your future, you will imagine your life. You'll imagine the scenery you've walked through, and you'll imagine the time you've spent together. You'll even imagine you growing old because you know that this is your ultimate goal of liking him, that is your ultimate desire to be with him.
When you like someone, you will have these strong "feelings". These feelings may confuse you, may make you feel miserable, and may make you feel happy. But in any case, these feelings are real and are all manifestations of your liking for him. So, don't be afraid of these feelings, don't run away from them, because these feelings are the evidence that you like him.
