Write a letter to your friend.In your letter :explain why you changed jobs,describe your new job
Dear jack:
I'm writing to tell you i have changed my job recently.Before i find new job,i used to work overtime so that I have no time to take care of my new born baby,And my salary is too low that it's stressful for me to live in high cost living city.That's why i change my job. My workplace is nearby my house.so that's saving plenty of time.And the work condition is great , i usually go to work from 9am to 5pm. i don't need work overtime at weekend.
Anyway, i have to stop now because my cousin is staying with me.She send you lots of love and is asking when we can all meet up.Soon,I hope.
With love,
Tina
