Notes

If one object 'says' something to another object (e.g., a button that, when touched, turns on a lamp), it is a good idea to use a very negative channel, e.g., <lsl>

   llSay(-5243212,"turn on");

</lsl> It is impossible for an avatar to chat on a negative channel, and extremely unlikely that some other object would accidently say something on such a channel. (Of course, the intended target of the message must be set to 'listen' on this channel.)
