Dearest PERSONS NAME
I just wanted to take a NOUN and thank you for taking care of my clients while I was out of the office for those NUMBER days.
Things at work have been so ADVERB END W/LY , busy lately - we sometimes forget to VERB and be VERB END W/ for those who help us the most.
I hope you have an ADJECTIVE END W/ week and have ADJECTIVE plans for an even better weekend.
If I can ever return the NOUN and cover for you while out, please don`t hesitate to ask.
Sincerely,
PERSONS NAME
