As a scholar I am interested in the philosophy of language, semiotics, call it what you want, and one of the main features of the human language is the possibility of lying.
“Don't speak evil of someone if you don't know for certain, and if you do know ask yourself, why am I telling it?”
“Men don't know much about women. We do know when they're happy. We know when they're crying, and we know when they're pissed off. We just don't know in what order these are gonna come at us.”
