Analogy
Making the Strange Familiar
Analogies use something that has no apparent connection to the object to explain something about the object. The main use of analogies in daily conversation is to use something familiar to explain something complex.
Pain
A melting ice cream
is just like a bleeding heart
which beating in pain.

Chili
Love is like a chile,
some people might likes it a lot,
but,
some people tend to stay away from it.
Sport car
You can live a life like Ferrari,
if you can earn that much of money,
but if you earn as much as a Kancil cost,
who says you can't be as happy as driving a Ferrari?
Love or pain?
If you loves her,
just go ahead,
don't just hiding there,
having pain in your heart
when you saw her with someone else.
Happiness
Happiness
happens everyday,
every minutes,
every seconds,
if you know how to appreciate them.
Love and life
Which one will you choose?
Without love,
your life wouldn't be complete,
Without life,
love itself can't be supported,
so choose one please.
p/s : FCM is like hell to people who are lazy, But it's like playground to people who are willing to spend time working hard.
I feel like I can fly and carry a rock with me
The lighting broke the rock into pieces.
First, you have to add some oil in the pan then put in the wood to fry.
