People should only cross your property lines if they have permission to do so.

In their simplest form, boundaries separate one thing from another.
The most obvious thing is property lines —the boundaries of where one property ends and the next begins, often marked out by fences etc.
In terms of people, your skin is a physical boundary between your insides and your outsides — the barrier between all your gooey bits and the outside world.
Personal, emotional, and relationship boundaries take this as more of a metaphor — but are no less real for that.
For example, not giving someone your phone number or e-mail address, because you don’t feel comfortable doing so, would be a boundary in your relationship with that person.
Trespassing is still metaphorically possible, and still not OK.
