Mike goes emotional

We all know that robots aren’t supposed to have emotions, as it is practically impossible to program all the possible combinations of situations. After all, 0s and 1s can’t really understand what feeling is like, but apparently the creators of Mike have tried their best to instil this inherent human aspect. Mike’s expressive eyes are the windows to his digital soul, where different colors denote his current mood. Red stands for anger, green is for happiness (I would normally associate this with envy though), while orange means he is on the verge of shedding some :’(. There is no explanation on how Mike arrives at those emotions though.
