At least we can hope. At least there are a few minority who
really do as they promise and more. These are the ones who inspire
us alot and give us inspirations. Nevermind the so many quarrels
and break ups you seen, don't you want to see some hope once in a
while to believe there are some things good worth cherishing and
fighting for? Hope and purpose. 
What is the use of giving his/her heart in the first place if
he/she is unable to love her/him wholeheartedly in the first
place?
Besides, 'seeing' her/him is only a matter of perspective. You can
still see with your heart, soul and mind. You can touch, hear,
smell, feel.
True, no one want a loved one to make such a big sacrifice, but
then I always remember in some shows or testimonies from friends
when they were asked by their partner, "How much do you love me?
How much would you sacrifice for me?"
They find it contradicting and a paradox to answer in words. If
your partner answer you, "I would die for you." Most likely you
would not accept it 100%, right? They always show it in actions to
justify their love for the person. Minor things like picking out
bones from fishes to tasting their first baked cake to crossing the
road where the person is in the direction of the oncoming traffic,
shielding you from the vehicles should there be an accident. Some
even contemplated the bigger sacrifices: protecting them from harm
and giving their kidney or blood transfusion or in this case -
giving their cornea.
The ultimate one is of course giving their lives for the one they
loved. The biggest testimony their loved ones can get from them. I
am still trying to consider the bigger sacrifices are more than
enough justified compared to my selfishness and even the ultimate
one. For the benefit of the people around me should I give my life
for them.
We will see the pain that comes with loving another person. No love
is ALL sweet and cuddly. That is only one side of the coin.
Understanding both sides of the coin will
help us gain better knowledge of love and to fully grasp the value
of love and happiness.
How can you taste love without knowing what is bitterness, sorrow
and hate?
