We don't have one, I keep telling the wife I can get one from up the road near the temple, there are lots lying, intact, on the roadside where the Thais dump rubbish and the dunny man dumps his load.
We do not have one either. Maybe my influence has moulded my better half's thoughts on the matter. Can't think why, all I have ever said is, "if you believe in tooth fairies its time for you to go to the funny farm."
