What's the most important?

one  day, Shadow asked Ghost about her need so that Shadow could provide it. Shadow has a habit to provide what Ghost need because she love her so much. Ghost just smile and said: 'I don't need anything from you...i just need you'
Shadow felt sad and said: 'I really want to be there with you, to feel your embrace and your kiss..but you know my situation, it's difficult...'
Ghost smiled, 'Yes, I know...'
Ghost known the situation and never meant to push Shadow to be there for her. She felt grateful to have Shadow in her life, even they never meet. But sometimes the need to see her lover was so strong, she couldn't deny. So she asked something that she actually known Shadow won't give.
'Can i have your photo?'
'What for? you promise to see me someday...you can see all of me there. and I will gladly show you everything', said Shadow.
'Can i see your eyes? just a piece of photo of your eyes...please', said Ghost.
it was silence for a moment...and then Shadow finally said:
'I will send my photo to you soon...'
Ghost smiled and said thanks to Shadow. she couldn't wait to see her lover's eyes.
the time running so fast, Shadow never forget to provide Ghost's needs but she never send the photo. so Ghost asked her once again.
'where's your eyes?'
'what? here! I use it to stare at your photo!', said Shadow trying to make a joke. Ghost chuckled. she always love when Shadow make a joke.
'Your photo, my love...'
silence.
'Why is it so important to you? we will meet and you can see me...all of me', said Shadow.
'You promise to send it to me....'
'Honey...please...'
'Why is it so hard to you to give the most important thing i need? I don't need anything from you...i just need you! Are you afraid that i will do something bad to your photo?', cried Ghost. she felt so sad and dissapointed.
'No...it's not like that. Honey, i don't want you to live in pain if we have to be apart someday...you know we can be together right now. I don't want you to always longing for me while your life must go on...it will difficult to you to forget about me if you have my photos. please understand...', said Shadow with pain in her chest.
'I know what to do with my life without you someday, don't worry about it...i just need you right now...before i lose you...is that too much for you? Please don't give me your promise and keep me hanging like this'
'I will give what i promise...it's just a matter of time!', said Shadow with sadness in her voice.

it's just a matter of time...we'll be apart soon, my love...all i ask was just a piece of photo. Ghost hang up the phone in dissapointment.
