By the way, today we're talking about online dating on our Speaking Club & I want to share on idiom with you that I really like - take smth with a grain of salt [to understand that something is likely to be untrue or incorrect] E.g. Take everything that’s said online with a grain of salt. It is all too easy to develop a new persona, make things up, etc., when online. In general it means that you shouldn't believe everything that you hear or see and you'd better realize that it might be lie.
