Instinctively blue.

It’s hard to tell in English but I’ll try...
Somewhere, not sure exactly where, there was a huge beautiful field, with green grass and blue roses spread all over it. Right on the middle there was a tree. But not a normal tree. This one was very high and blue, all blue. Its stem, branches, leafs and fruits were completely blue.
After a while observing it, I could notice that just blue birds could rest on its branches. It seemed that any bird of a different colour knew, I don’t know how, the tree was not for them. Instinct thing, probably. I dunno...
When I got closer, I also noticed there were two little boys. One of them on the top harvesting its fruits and the other looking from the ground, holding a basket full of them. It was weird because they were both laughing and didn’t give a shit to my presence there.
Very curious, I then asked:
- Hey kids, what’s going on? What’s funny?
Suddenly they just stoped laughing and looked at me with a very serious face, giving me no answer.
- Can I taste one of these fruits? - I asked again.
- They are blue fruits. - Said the little boy holding the basket.
- Yeah, I know… But can I pick one and eat it?
Then the boy on the top of the tree yelled very angry:
- But they are all blue fruits from the blue tree!!!
- So?! What’s wrong about it?! Can I taste or not?! Just one!
They suddenly started to harvest the fruits again, laughing even more.
- Shit, what’s wrong with you guys?! Are you retarded or what?!
Then again, no answers. All they could do was laugh and keep harvesting the bloody blue fruits. For a moment I thought that probably just blue people could eat it and, as the birds, I should naturally know that and avoid it. But they were so beautiful and blue that I couldn’t resist... I just didn’t give a shit and got one fruit from the boy’s basket. It was beautiful! Very blue, soft, rounded, as big as my closed hand and with no marks or imperfections at all! The smell was just terrific!
(too big, I'll tell the rest another day).
