HOHO! Before I started my late night studies, I just want to type out something to make myself feel better(:

"The past is still worth thinking, as it carries certain memories;
however, it does makes sense to care about things that you can control;
instead of things you cannot control."

The past may be reversible, but like the technology of Science, how the eventual distant future that will descent upon us, depends on the users themselves. If a spark does ignite the wick of the candle, allow it to burn. For, this candle will forever be existent in my heart. (:

AH! I feel much better. The meanings behind these words are for everyone to decipher. (especially you)
