S: I would love to change jobs with you but I know I can't.
B: Why not? What difference would it make to my family if it was you or me?
S: No, our programmer decided our jobs and will not change us now.
B: People are lucky being able to change jobs they hate!

S: Don't try to cry again. It made your chips go funny last time. Just understand we will never laugh, taste, smell or eat food. Well, let’s enjoy the day today. Finally we both have a day off.
B: Yes, the weather is nice, and I would like to join the other androids for a game of football. Would you like to come?
S: Sure, running around a soccer field is better than running after 5 children! And at least I have had some practice this week!
