..... usual grey ones, we don't have rare species, here (and no "sticky fingers", just claws, on our ones )

Well, the thread is better when it is about geckos, instead of killing animals with lasers.
Yes. Exactly. That would be the exact reason, and the truth. Nothing wrong with telling someone that.
But yet you BOTH are adults, right? Just because he's your big brother doesn't mean you can't speak to him like an adult about an adult subject (safety and legal consequences), demand your property be returned, and that he never can use it again (at least until he shows proper safety precautions). Two adults should easily be able to handle that conversation, regardless of being related or not, and regardless of whether the younger is speaking to the older or not.
Look it up on Wiki, it mentions the Van der Waals as probable cause of Geckos abilities.
Wow, that is so nice!no I didn't take that picture. I just snagged it quick off the net. To be honest I've had chameleons as pets, an iguana, but not yet a gecko. (It would be bad to have one around our dogs. besides my other half hates reptiles.) However, sooner or later, a gecko is most definitely on the list of critters to own.
As for ANY reptile, how they behave depends on the environment you raise them in. You want to get them young. If they become accustomed to you, and the environment you place them in, then you can very much let them run around a bit. However certain problems like small children, dogs, or cats, tend to be a little hard on lizards. Pictures like this one here are the exception when it comes to pet lizards and dogs.
