Rade- seriously, you are wrong. Machines are perfectly capable of both feeling and understanding emotions. The films make that perfectly clear ('Love is a word...'😉. So that line is unhelpful. They are sentient, just like you and your friends.
Not ALL Machines- some are not programmed to- but plenty are.
Also simply refusing to answer a question is a failure to engage. You cannot dodge the question on the idea Melitus will not understand- trust me, he will.
Your first paragraph makes no sense, Rade. If something just 'is' then it is true. If the love was false it would not be genuine and so it would not really be love. People CAN be fooled into thinking they are in love when they are not, you see it all the time. You canot divorce love from false or true- EVERYHING can have those terms applied to it. The second half of you statement goes towards saying it is true, as social interactions are the same.
Fire, in that case, Melitus wishes you to replace 'love' with 'friendship' and apply the same criteria.
