Letter

I needed to write a letter about myself for homework and i was given this plan:
1. your name, when, where you met your friend
2. appearence
3. personality
4. hobbies, interests
5. conclusion about myself.

I'm not asking to do this homework for me, i've already done it, but guys, could you take a look at it and correct all the grammar, time and the other mistakes i made? THANKS.The letter is below...

Dear Alex,

I'm not sure if you remember me, but we met at the basketball match few years ago. We were sitting close to each other, yeah, it's me, NAME. Probably you don't know much about me, so i want to introduce myself a bit and i hope that i'll get response in which you'll do the same, thus we can know each other much better.

I'm relatively normal height with an average body-build. I have medium, brown, straight hair and green eyes.

My personality is kind of hard to explain, but i'll give it a try. I'm responsible, reliable, and hardworking - I get the job done. I'm also loyal and honest. If I commit myself to someone, then i'm fully committed. I'm trying to connect optimistic and pessimistic outlooks on life into one.

One of my main interests is sport, actually basketball, as you may have known already. I go to as much matches as possible and which lefts, i watch it per TV. Also i like european fotball and rarely i like to watch boxing. Without sport there's only much small hobbies.

So as you can see i'm pretty hard to understand man. People, who don't get me, they see me as boring, conservative, and egotistical, but i see myself as decisive, stable, and dependable person.

Best Wishes,
NAME
