"Write your first letter to a penpal"

Dear Michael,
You are my first penpal in a long time, so forgive me if I don’t remember how to do this correctly.
My name is Helena and I was born in Galicia. I’m 23, I’m not very tall and I have green eyes. My hair is dark blonde and most of the time it is really messy.
I’m learning English because I think it is a really unique way to be able to embrace many languages and cultures.
Where are you from?
I’m an optometrist and I have been working in an optical shop for almost two years now.
What are your plans for the future?
I like all kind of animals, except for insects… I have a pet and I really love “him”. My dog is called ‘Son’, which means "sound" in Galician (You see? My family and I are really into music).
He is a Spanish Mastiff and he is really big!
Do you have any pets?

I really hope you liked my letter, as I said before, I’m not used to writing them anymore. I’ll be waiting for your answer.

Yours sincerely,

Helena
