Bad behavior! When you are interested by someone, you can do many things to get her. Let's me tell you a little story to explain what I'm saying. When I saw her for the first time, she was the only girl who I'm interested in. I decided to speak with her and as I'm not bad if you know what I mean... that matches between us. So, I took her number and we began to get to know each other, everything was great. I did everything to make her laugh and she liked it. When she wanted that we meet, I always managed to be free. Then, what had to happen, happened. She began to love me, and me, I felt comfortable about it. ( because I already got what I wanted) I began to be less present, I had not the time to meet her anymore, and her smile became occasional. I when to say, why do we take time and energy to get a girl and we do not do more to keep her? That seems weird, right?
