Men are more straightforward than women, who can be called masters of hints and gurus of charades.
Basically, representatives of the stronger sex say exactly what they want to say, without adding any other meaning to what they say. But it cannot be said that this happens absolutely always.
It's not a man's business at all - your partner simply can't explain what he and his friend talked about on the phone for two hours or what he did last Sunday.
It's not always about shameful or personal things - most likely, it's too stupid, and the man doesn't want his companion to know about it.
Stop panicking - this phrase does not mean that your betrothed intends to leave you for a girl he sees for the first time in his life.
Men often evaluate women as works of art – just as magnificent, but unattainable. Would you be jealous of your partner’s Venus de Milo?
According to women, this phrase contains a sea of hints and thousands of mysteries, which is why all sorts of thoughts creep into their heads - maybe they should be offended, or maybe they should ignore it?
In reality, everything is much more prosaic: your man most likely trusts you completely, and perhaps is not able to make a choice on his own.
