Colds and Helping the Vietnamese

We're both fighting colds a bit at the moment, i think it may be a combination of weather changes (everyone here seems to have colds) and getting used to the city pollution. Hugo slept most the morning and i havent done much more!
Just a quick story from yesterday:
Theres a restuarant we have been to everyday since being here (meal for 2 + drinks= £5-6) and have got to know the owner and all the kids who work there. We have been offering low priced informal English lessons for locals, and was chatting to her and her daughter about it last night (she already knew as one of her staff had asked us about teaching them the week before). We were explaning how we didnt want to price people out of an education. The owner (Mai) said "i understand. You arent trying to make money but help the vietnamese people. Thank you for helping the vietnamese"
That meant a lot to us.
