Pete, we also get the odd snake or two, but thankfully the dangerous ones tend to prefer it outdoors....lol.
You can buy those door seal strips at quite a few places in Hua-Hin, and in fact, I've even seem them at Tesco in the past.
BTW, when your maid leaves the doors swinging open, it's not because she prefers it that way, but instead, it requires less energy than what would be need to actually close them
I have the same problem with my wife's Mom - she'll open a window, and to date, she has never put the hook on prior to the window slamming against a wall in the wind. Do you think she'll learn that this can be prevented simply by using the hook in the first place? Not a chance in hell. Of course when the window eventually breaks, I'll make damn sure it's her that pays for the repairs. If you ask me, there are only two possible reasons for doing such things...........you either have to be unimaginably lazy, or totally and utterly ...........

Don't try to impress me with your manner of dress cos a monkey himself is a monkey no less - cold fact
