One of the nicest things about Guam are the geckos, small lizards and skinks. There are dozens of the little creatures which have free run of everything. There's no way to keep them out of the house. They can get through the tiniest of cracks, hang upside down on the ceilings and move quicker than anything I've ever seen. They hold territorial wars on the walls, live behind anything that hangs and chatter all the time.
Geckos make two distinct noises.
One sounds for all the world like your old granny tsk, tsking you when you do something wrong. Legend has it, when the gecko makes this noise, its unhappy with whatever you are doing. The other sound is similar but is more like a cheerful chirping. If you hear a gecko laughing at you first thing in the morning, you are in for a great day. I'll miss that sound a lot if I ever leave here.
