Friends, don't wait for things to happen and you regret.
Somethings you done can hardly return to the same state as before.
Somethings may comes by easier than you thought, making you take advantage of it.
When it comes to an end, you thought its ok but I can tell you; its not what you thought you will feel; not what you thought you can throw away easily.
Its hell alot harder.
Its alot more heavier than you can carry, it can be so heavy till you don't feel like moving on.
Please don't wait for it to end and regret.
a temporary reunion = a permanent ending of relationship.
