Some things in life that people do, are just not meant to be done a second time. I think everyone makes wrong choices in life. One encounters in life some choices that may lead down a positive road or just may lead towards negative consequences. No matter the situation, everyone wishes he/she could do it over differently at one point in life. Imagine, if you had a chance to do just one thing over again, what would you do?

Throughout my life I can say, mistakes have happened/or have been made. I have found myself stuck in many situations were one wrong choice, lead into something fatal. Growing up as a child may not have been the easiest thing to do. When I was younger, one may have not considered me as the most affectionate person. In my opinion the way I dealt with my personal relationships was, I would not have to tell a person a million times that I love them, it was always presumed on my part that they should just know. Neither I nor anyone else around me understood why it was so difficult for me to express my emotions to the ones I loved. This made a number of close relatives and loved ones very upset. They always thought just because I cannot show affection, would directly translate to me not loving them. That was never the case at all. The older I had become, the more I realized how many people around me I was hurting. This progressed into a larger problem. I hurt people unintentionally. About 7 years ago, my grandfather passed away unexpectedly. Since I never expressed my feelings much, I feel as if he died without knowing how much I loved him.

If I were given the chance to do things differently, I would express my emotions and affection to the people I care for more often. I would not only change it for others, but change it for myself. My life represents a roller coaster. Some days my feelings show more than others. I know that if I were to become more affectionate, it would make not only myself. but others around me realize how much I care. I am sure my grandfather knew I loved him without me having to tell him. I just feel as if I were given a chance to do it differently, I would make sure I told him how much he means to me. Even though I am not one to regret or try and change my past, I know this one thing would influence my life for the better. Having examined my past, I concluded that I will make sure I do not hurt anyone unintentionally, and make sure I let him or her know how I feel.

Prior to today, I never realized how important it is to tell some one how you feel about them. I went through a big portion of my life assuming the people around me knew I cared for them. I never thought about changing my past to do it differently, because one thing done differently can change your entire life. Since I went through 7 years of my life living with this awful feeling, I would in fact try to do things differently. So in conclusion, do not wait to show someone you care, because life is too short, and can be over in a second.
