Crossing arms.
This one shouldn’t come to you as an amazement either. When you fold your arms, you show a close non-verbal communication or body lanugage and this tells a lady “Don’t approach me!” I have seen such a large number of fellows do this in clubs, it’s alarming (now and again notwithstanding for the young lady). Consider it, when was the last time you saw somebody fold their arms and laugh? Generally individuals fold their arms when they disagree with somebody, or when they are cold.
When you approach a lady who has her arms crossed, your first objective ought to be doing everything so she uncrosses them.
