If you knew they didnt want to do it

[denuseri]

A slave (who therefore may not be allowed to have any hard limits under the definition some use) has a health problem that precludes certain activities... do these activities now count as 'hard limits' or are they kept as 'things the Dom/me could do, because the slave has no hard limits, but will not do out of respect for the slave's state of health'?

Only a fool builds a house and then tears it down the next day.

Only a fool plants a garden and lets it lay fallow or go to waste.

So too is it between masters and slaves.
