Always recall the incident on Soi Post office (years ago) of an English guy lighting off a large firework he had bought, and it appeared not to go off, and he went back to it to take a look. It blew his face off. I have already had my neighbour set off a few, completely unconcerned that he could set homes on fire... there is overgrown and very dry land behind us.
Drunken fools, Thai and otherwise, will be at it again in a few days.
