Don't force a pc who is ill. The whole intention when auditing a pc who is sick is making him well.
If overts, or M/W/Hs don't read, even though he is nattering, then they are not available to be run right then.
A preclear who is not well cannot look, his havingness is down and he must be handled permissively — always.
The mechanism of release must be well understood to make an ill person well. They plunge down the track madly on any excuse. They require much lighter auditing than they stand up to when well.
