What does it mean that boundary flexibility is not boundary weakness?

Adjusting boundaries based on context is different from abandoning them under pressure.

Example: A team lead has a boundary: no work messages after 8 PM. A production outage hits at 9 PM on a Tuesday. She responds, coordinates the fix, and goes back offline by 10:30. The next morning, a colleague jokes, 'Guess the no-messages-after-8 rule is dead.' It isn't. She adjusted her boundary for a genuine emergency — a system down, customers affected, a time-critical response. She didn't abandon the boundary because someone sent a 'quick question' or because guilt made her feel she should always be available. The boundary still holds for the 95% of evenings that aren't emergencies. She can tell the difference between adjusting and caving because she can articulate the criteria: severity, time-sensitivity, and whether anyone else could handle it. A boundary you can adjust deliberately is stronger than one you enforce robotically.

Try this: Identify one boundary you currently hold rigidly — something where you never make exceptions. Write down the boundary, then list three hypothetical scenarios where adjusting it might be appropriate. For each scenario, write: (1) what contextual factor makes this situation genuinely different, (2) what the adjusted boundary would look like, and (3) how you would return to the default boundary afterward. If you cannot identify any scenario where adjustment makes sense, examine whether the boundary might be functioning as a wall rather than a gate.
