Hi there Long,
We still talk about our trip and tell our friends what an absolutely fantastic time we had. It was so wonderful to hear from you again .
The families are fine and we are still working hard – no doubt, much like you. How is your family – all good we hope.
Thank you for the arranging tour in VN and we will pass on your contact details if we hear of anyone planning an overseas trip. Our holiday that we had with you was a real holiday and you looked after us all so well – you should be very proud of yourself. I wish you all the best with the business, please keep in touch and drop a line every now and then.
