Write a letter to your friend expressing your feelings about earning your first wage.
Dear Cooper, 
I hope you have been in good health since we last spoke. I'm excited to inform you that I've just finished my first month of employment with AMG Auto Motors and received my first pay check. The amazing feeling of being paid for my hard work is truly surreal. I feel fortunate to have found a job that pays well for doing something I genuinely enjoy. I hope to save enough money now to buy a car to plan a trip together.
Best regard, 
Simon.
