Thanking Note (一般英语不习惯说感谢信,都会写个类似于小贺卡的note)
Dear XXX,
I am writing this to express my sincere gratitude to your kindness. It is very nice of you to pay a visit when I stayed in hospital, I felt warm and relieved when I saw you. I attribute my quick recovery to your care. I wish to keep our friendship forever!
Thanks again and take care!
Yours,
XX
