You know, all of us need human contact. Words exchange, listen and to be listened, touch and to be touched. You may deny it, but than you are wrong.
Even introverts, like me. We also need to be in contact with others. Of course, level, amount, number of people… so different. For me less is more but this definitely is not valid in general.
So act as you want. Choose your social attitude and behave according to it. But remember, there is no Robinson Crusoe selected by himself.
And the selected photograph? Focus on the man on top of the tower. He is alone but not lonely. He is smiling and his friend, family member (who knows?) made two steps and is not visible anymore.
Do not decide or accept the first impression. And even worse, do not decide based on opinion of others. Make your own. And give a second chance.
