Be Afraid of Unknown Person

This is the true story of my life, and I am sure everyone had ever gotten the same experience. For me this was a bad experience that I ever had. At first, when I met somebody else, I really interested in him. Sometimes somebody looks so kind at the first meeting, doing anything for you, and leaving you. I really don't know what the purpose is, why bsomebody do that and in the end he/she will hurt us, it's so dissappointed!!!! So, please be carefull of unknown person, cause they could injured your heart. Don't be easy believing someone kindness, nobody knows how his heart is. Yeahh... bad experience should make us better.
