Asking your former teach to write a letter of recommendation

Dear Mrs Thompson, Hope you are well and healthy. I have been thinking of writing for a long time but could not due to a hectic schedule. I have recently applied for the job of an English teacher in Thailand. As you may be aware I am very fond of teaching and I always considered it my passion. Having completed my graduation, I came across this opportunity and applied for it at that very moment. I had a Skype interview as it was not possible for me to travel all the way to Thailand just for an interview. However, it went very well and I was offered the position. Will you be kind enough to write me a reference letter for this job? Please can you include information in relation to my character, behavior and trustworthiness. Teaching is something that I always wanted to do and I always look up to you as a role model and I’ll like to teach in the same manner as you. It is a once in a lifetime opportunity. It will not only give me a chance to pave my way in the world of teaching but also enable me to learn about new cultures and tradition. Lastly, can you please mail me the letter within 10 days as I need to post it to Bangkok. Thanking you in advance and looking forward to hear from you. Yours sincerely Shashi tharoor
