Does Love need reason??

Lady : Why do you like me..? Why do you love me?
Man : I can't tell the reason.. but I really like you..
Lady : You can't even tell me the reason... how can you say you like me? How can you say you love me?
Man : I really don't know the reason, but I can prove that I love you.
Lady : Proof? No! I want you to tell me the reason. My friend's boyfriend can tell her why he loves her but not you!
Man : Ok..ok!!! Erm... because you are beautiful, because your voice is sweet, because you are caring, because you are loving, because you are thoughtful, because of your smile, because of your every movements.
The lady felt very satisfied with the answer. Unfortunately, a few days later, the Lady met with an accident and became comma. The Guy then placed a letter by her side, and here is the content:
Darling,
Because of your sweet voice that I love you... Now can you talk? No! Therefore I cannot love you.
Because of your care and concern that I like you.. Now that you cannot show them, therefore I cannot love you.
Because of your smile, because of your every movements that I love you.. Now can you smile? Now can you move? No, therefore I cannot love you...
If love needs a reason, like now, there is no reason for me to love you anymore. Do love need a reason? NO! Therefore, I still love you... And love doesn't need a reason.
