Never mind points of view. It is a mistake to suggest that 'any girl' in her right mind', as you said, will go for that sort of thing. That is simply not a statement concurrent with the real world. Many girls in their right mind will loathe it.
I very much hope his girl liked it but there has always been a certain lie floating around in the world that to express your feelings in such a way is a superior form of showing your romantic side. It is not; it is a form of expression like any other and a smile, a touch at the right moment or even a 'buzz' is worth a lot more.
And I am afraid it is true about the laughter. Endless polls have shown that finding a partner who can make you laugh is one of the most sought-after things in a relationship.
Now if things went the way I wanted or imagined I would be oozing and dripping romantic sentimentality from every pore when with a girl. But I do not because I had to very quickly learn how appallingly counter-productive that is.
