'Forever' is like a book. Some don't like to read, some loves to read. The ones who read don't always believe it. Some do, some just don't. Some who believe will just achieve something, the ones who don't will gain nothing.
The word 'forever' sounds both incredibly beautiful and hypocritical. It is beautiful for those who love. It is hypocritical and it sounds childish for those who ever failed in love.
Some say: "How could you say 'forever' when we don't even live forever in this world?"
Maybe it's not forever in the actual meaning of it. Maybe when someone say forever, it just means for their whole lives. Like.. Who cares of what will happen after they die? It's not their choices to die, anyway. It's not within their control, too.
Maybe I believe in forever, but maybe, just maybe after the word itself turns into "along this mortal life".
