Red.

Buddy, we all know when the birds prepared themselves migrating to the south, there would be no words left for me, not necessary. This is getting cold, buddy, thinking whether we could pass the winter together or not, even though we know, absolutely know, this is not winter yet but rain came down and hit my windows this afternoon, and what about you?

Buddy, a package arrived in front of my door last week, neatly wrapped with a blank red paper. I once thought it was from you, but in a matter of seconds I knew it wasn't. So, what was so important?
But buddy, there would be no package sent to me from you and on the next day I constantly started to wonder who the sender is and if I wanted to open it, it might happen, open it.

But the problem is when you put a very good package in some 24 hours and keep it save in the drawer, untouched.

And buddy, when all the leaves fell to the ground, I realized.
The thing was someone had opened the package for me, since I knew....

....my letters were not about you anymore.
