Dear Ms Melancholy
It was so good to see you again last week and lovely to meet your family.
I hope you all recovered from the lack of sleep/food/jetlag and had a lovely few days in the city (How was the Grand Palace? Did you get to the snake farm?) I hope the trip down south was easy.
Thank you for the hospitality at your hotel. I hope that I was able to help with protocol on tipping in Thailand, recommending good dishes (please try Larb Moo: spicy pork salad) and explaining that Thai dishes arrive when they're ready rather than coming all together. I realise that this strictly contravenes Melancholy family rules and hope that on your return you will be able to reinstate this well mannered behaviour in the children. Whilst on this subject, please accept my apologies for insulting your husband's bathroom building prowess, eating his dinner and making your son cry.
It was probably as well that you were all tired/jetlagged and that I disappeared when I did. All in all it was a wonderful evening!
