I think the general observation is correct, though. If a woman has the slightest interest in a man, his touching her arm will encourage the interest. Even a highly married woman such as myself will sit up straighter and mind her pitch when an attractive Latino gentleman gives her a pat on the arm.
However, I tell my teenage daughter that this doesn't apply to her: if she even smiles too hard at that vaquero in the fancy boots, either they're engaged or his girlfriend will try to kill her.
What is ... nevermind.
