you give a pretty definite answer,
which is that the answer is between the questions.

I can't quite decide whether this is profound or trite.

But I do know I don't like poems made of questions. It is far more effective to make your poetry raise questions without asking them.

as jess says - all the question marks take the reader's mind from the write

i have a couple of suggestions for better grammar :)

Or solitude has always been in us?
- Or has solitude been always in us?

Or shadows and lights are reflected from us?
- Or are shadows and lights reflected from us?,

I think I still need to learn prettily much.
- I think I still need to learn much more.

a good write i think
pertinent and interesting questions

"I think I still need to learn prettily much."
..i think it sounds better when you use the word "pretty"?! as for the questions..it gives the reader a lingering thought, before proceeding to the next line..which i like the effect on me.. ;)
