Is it a good idea to talk with your target about body language?
for example:

-pointing out her body language that indicates her attraction to me followed by "i should be on my guards"

-pointing out her negative body language followed by "you look nervous, i usually don't eat well-behaved humans don't worry"

-DHV your skills in detecting body language by analyzing other people's body language around you including humor like "she crossed her arms, he probably asked her if she wanted to have a threesome"

so is it a good idea? if so, what's your versions
