Can you do x,y and z & return it to me?
(does y and returns it)
Ok, thanks, can you do x and z & return it to me?
(does z but undoes k and m in a different section)
Umm, ok, please put k and m back the way they were, and x also still needs to be done please.
(puts k back but changes m to something else wrong but still doesn't do x and returns it)
Please make m the way it was before you first changed it, and again, please do x.
(fixes m, does x, and undoes y.
[me, jumping out the window]
