Letter to D

Have you thought about that perhaps we can't meet again? The chance to meeting people again whom I met while travelling again are very low. Whenever I write a letter to you, I feel like I'll never get a chance to meet you forever as well. Maybe I can see their life on Facebook, but we don't even Facebook each other. We just are connected by letter. I always send letters to you, but feel depressed because it seems to ends someday. Do you think we can't meet each other permanently? Our meeting was just an accident that happened casually? If I don't send mail you anymore, do we become a strangers again?

[Good work.]
