Hi Mike

Are you still living at the same house.  I drove past the other day on 
my way into Osborne Park and it seemed neat .

Can I drop over soon to have a look at what you are up to with the car?

I am working from home as of today. Contract with Nautronix wound up. I 
think there is going to be some staff shedding shortly.

Sad, but thats the way it goes. Fortunately I have enough work to carry 
me through to New Year.

Cheers
Don
