Dear [Mother's Friend],
I hope this letter finds you well. Thank you for your kind offer to let me live with you after your return from abroad. I am truly honored that you thought of me.
However, after giving it some thought, I have decided to politely decline your offer. I hope you can understand that it is not an easy decision to make, but I have several reasons for doing so.
Firstly, I appreciate your generosity, but I feel that I need to be independent and find my own way in the world. Living with you would be comfortable, but it would not allow me to grow and develop as an individual.
Secondly, I have other commitments that require my attention, and I am not sure how I would be able to balance them with living with you. I have a job that I enjoy and friends that I care about, and I do not want to lose touch with them.
Finally, I value my privacy and personal space. Living with someone else would mean that I would have to adjust to new living conditions, and I am not sure that I am ready for that at this point in my life.
Once again, thank you for your kind offer. It means a lot to me that you thought of me. I hope that we can continue to maintain our friendship, and I look forward to hearing about your travels.
Sincerely,
