Like what you've said, it is impossible for us to stay as close as we used to. Sometimes we get even closer, while at other times we just get more distant. Therefore, I used to feel really sad when such situation came. I guess I have learnt from them that actually there's no need to be afraid. Because, whats most important is not how close we are in the end, but rather that we have kept all these wonderful memories close to our heart. Cos everytime we recall them, we'll noe that we have given it all that we have and not have any regrets.
Seriously, I don't need you to tell me how much you'll miss me, I don't need you to tell me how sad and lonely you'll feel without me, and all the more, I don't need you to tell me that you'll never forget me. But I really really need to hear you say, to hear you tell me that I been a great friend. Then, I'll know that I have once played an important role in your life, and I'll know that I have always been by your side when you needed me.
