Re: I still get wound up...
Am I the only one here who understands the definition of TRESPASS in this context to be "entering another person's land or property without permission"?
If you have permission, then you cannot be trespassing by definition. There is no condition which exists as the opposite, you can't wave to someone from the window and say "It's all right, you can trespass in the garden."
And this is why the sign annoys me. And why I'm getting wound up by this thread now! I wish I'd never shared that.
