‘Oh Zalbotron,’ said Gretta, sadly. ‘And I thought we were friends.’
*I HAVE NO CONCEPT OF FRIENDSHIP* *I AM PROGRAMMED ONLY TO KILL* Gretta put a hand on the robot’s shoulder.
‘Don’t be so hard on yourself,’ she said. ‘I’ll be your friend.’ The robot whirred for a second.
*I WILL ATTEMPT TO KILL YOU*
‘Well, if we’re going to teach you about friendship, Zalbotron, the first lesson you need is that friendship is all about forgiveness.’ She smiled. ‘I forgive you, Zalbotron, and I’m sure you won’t try to kill me again.’
‘Silly old Zalbotron!’ laughed Gretta. ‘You do say some funny things! Come on, let’s go and leave you unattended near the life support computer.’
