My job

I definitely liked my first job in my country, Latvia. I worked in a big factory. I was a van driver. I delivered our product everywhere in Latvia. Also, I did some presentation of our product. I was enjoyed my job a lot because I met a lot of people, I saw a lot of places in Latvia and I liked to communicate with people.
I am missing my job so much.
