Nothing lasts forever. I am happy to share some moments our lives together. This is what I think, though. You are going to be drawn to come back and when you do, I will be here to welcome you. I would like the same thing if I left for a time, to have a familiar face to greet my return.
Are you seriously planning on leaving? I might not come on that often, but really? Life has more pull than the internet does and I understand that, but this is an outlet to friends you could never meet in real life easily. If you are leaving, then I wish you luck and good fortune in your life. Make your future something worthy to look back upon.
