Dear Mother,
How are you? Everything is well at my end and hope the same with you. In this letter, I wanted to tell you about today as today was one of the most hectic days. Because of the Independence Day celebration, I was very tired since yesterday. And today my maths teacher had asked us to complete the assignment tomorrow itself. Although I've completed the task but have become very tired.
For now, I’m ending the letter. Will talk about it more in another letter. Take care of yourself.
Your loving son
XYZ
The answer to your question would be, “to show that despite its differences, America is still a country that unites in times of strife.” Hope this helps!:)
