What are 3 reasons for the authors purpose of writing thank you m and rsquoam?

It seems like you might be asking about the purpose of a specific piece of writing titled "Thank You M and Rsquoam." However, there's no widely known work with that exact title.

To help me understand your question better, please provide me with more context:

* What kind of writing is it? (A letter, a poem, a story, etc.)

* Who is the author?

* Do you have any information about the content of the piece?

Once I have more information, I can try to identify the author's purpose for writing "Thank You M and Rsquoam."
