Thank you for your letter and for the recommendation letter in advance. I am sorry for the delay; this is because I didn't check my email frequently.
I am fine, restudying my English, practising, listening, writing and speaking. Of course I also enjoy life with myfamily these days. I have travelled through/around/to several cities during the May Holiday. It was fantastic. But now I think it's (the) time to return to work. That's why I needed your (recommendation) letter for me to secure a job.
I had a really good time with you and all your other colleagues at XXX company; if possible I would also like to work for the company again. However, I'd prefer the same type of work as I did before. If you have an opening could you please recommend me for it? Thank you!!
How was everything on your business trip? How's Dan? If he still likes to play tennis, I could recommend a perfect teacher for him. I hope that everything is going smoothly for you.
