I definitely tend to mine. Sometimes my personal boundaries are like the Berlin Wall. But not usually.
In certain respects, there's no entry or it's very limited.
If you have strong personal boundaries, you're more likely to respect other people's boundaries.
Those are the hands-off, nose-out-of-my-business kinds of boundaries. No wandering hands, no prying eyes.
Other boundaries are more mental, your field of operation, where you range and how far you range.
