exactly, timbits...

and I want to stress the following (I remember about it this morning and this is a great place to state it):

IGNORE bad behaviour AND PRAISE AND ENCOURAGE good behaviour.

It DOES NOT MATTER at this time WHAT the bad behaviour is. IGNORE IT.

If you can not see obvious GOOD behaviour, seek it out in him. When you see it, compliment him on it or otherwise support that behaviour. IT MUST BE REAL AND GENUINE.
