"Please rest in peace, our sunshine"
If you haven't said these words yet, you probably haven't understood someone's worth. Think about it, have you ever repayed this individual who once gave you warmth? Have you ever thought that maybe there was something you did that was probably hurting them? If there is something that you might be doing which is hurting them, then please hurry up and give some warmth to them as well. Change and do something good for them before the sunshine of your life has melted into the horizon forever.
