Hello. I wish to write a very appreciative thank you note to an Italian teacher who had willingly helped me in preparing for my French speaking exam even though she did not have to. However, there is a problem with this since I have absolutely zero knowledge of the Italian language. I want to say in my note- 'Miss (surname), I wish to thank you very much for all the sacrifices that you have made in order to help me prepare for my French speaking examination even though you did not have to and have not spoken the French language with another person for around twenty five years. You are a great person and I wish all the best for you in life. Yours sincerely and gratefully, (me).' Thank you.
