Dear Panita,
I’m still sad to let you go, but at the same time I’d like to wish you and your family doing very well in future. I believe you have made the best decision for the family. As always, family come first.
Glad that we have had really good working time and relationship throughout last 10 years (almost!!). Form the time we don’t really know each other to our current good relationship that more than just a co-worker, but good friendship. Went through all the ups and downs.
Thank you for all the efforts you put in and again wish you all the best!
Take good care.
