Is it possible to get writer's block when writing about past events?

I'm currently suffering from that but it may be caused by the lack of memories that I have up until third grade.

This was probably one of my best years, in school history.

It's when I transferred to  Elizabeth's elementary school which went by the name of Peterstown School #3.
I was the new kid, but with 9 years of age, I didn't understand how nerve wrecking it can be. I adapted to pretty well to the area, and to the people in my class.

I made one best friend during the journey. Danairy and I would want to sit together all the time, though our teachers insisted on assigned seating. I got moved from Danairy's side to a desk next to these two guys.

Now this is the some what interesting thing in my third grade story.

See, I was always picked on because of height, weight, etc. So I didn't really expect any guy related business until I fixed all my flaws.

To my ULTIMATE surprise, Kevin and Luis weren't like the other kids. Actually no one was in that class. Everyone was nice to me, and greeted me into the class as if one of them.

After a while of sitting in that same desk, I became close with both of them. And even acquired a friendly crush for both, even though I knew that it was Luis who I really liked.

Nothing happened, but ; even at my age at the time; I noticed that there was a chance he can like me too, but neither of is acted on our feelings, I mean...I was 9!

Too young for anything.
Hell, I didn't even know what sex was up until this year. I over-heard a conversation between these two girls and they mentioned "sex".

Sex? What's that? A game?

I was so naive and innocent. A lot of us were, but others were far more advanced.

After getting my heart repaired, learning a new phenomenon, and making a new best friend, I was ready to pass to fourth grade.
