You are so right about trying not to put what you saw in romantic movies into real life practice.
This is exactly what a lot of people do and they get bad results because unfortunately their partners are not well trained actors
Those movies they watch where directed and produced by people who have been selected and auditioned with their voice and their physical features and they are actually following a well written story which is aimed at advertising either a product or a culture.
Unfortunately many of us buy the idea and hope to use it on fellow human beings.
Somewhat wicked but I must say it's a trade of culture.
