Knowing that you way loose someone dear make you think back. All the time you spent together all thoughts, funny and hard times reveals and you understand how much you will miss them. But at least its better than when they leave life before their time was there.
Some people is so close already from the beginning of your life that you always had them in the heart, other you have to let in and its hard to open up your inner self and then see how a part of you disappear when they leaving.
How many times can you open the heart.
