When adults stop playing in the sandbox, they simply become lonely. Is everything simpler in childhood or does it seem simpler? You can play in the sandbox, exchange shovels, and make Easter cakes together. There is also hide and seek, swings, playing house, or you can just do nothing, be nearby and feel happy. When do we start making life difficult for ourselves? Decide something for others, read their thoughts and expect actions that others may not even be capable of? The most important thing in these SKILLS is that gradually the game, friendship turns into CORRECT SOCIAL COMMUNICATION, into endless conventions. This is “acquired skepticism,” the experience of first disappointments and betrayals. Now you have learned to communicate correctly and safely, but your friends are becoming fewer and fewer. Life has scattered old friends, but we keep new ones at a distance. A great way to make yourself a little lonely! No, life experience is wonderful. Learning from your own and others' mistakes is also not the worst way to grow up. However, what do we end up with? Friendship is now at a distance, but love has rules. Everything's under control! Only such security has a side effect: discomfort appears, dissatisfaction with oneself or life and the feeling that something is clearly missing. Then begins an intense search for something to do with oneself, find a hobby, have an interesting vacation... But time passes, and the discomfort does not go away and there is no treatment!!!And so, we remember how happy we once were, how carefree we played, had fun, believed and forgave, cried and laughed together. All this was and happened naturally, just like that, mutually and without demanding anything in return. So what makes us stronger and happier, heals us from adversity? The most important thing in our life is close relationships. Yes, yes! What heals us is heartfelt friendship with someone who truly cares about us. When we are going through troubles or suffering from someone's hostility or loss, then friendly sympathy and advice can be the best medicine. Openness with a loved one is good for the soul and body. Authors of more than 80 studies have concluded that social support has a positive effect on the functioning of the cardiovascular and immune systems (Uchino et al., 1996). We all want reciprocity, and this should not be neglected. You shouldn’t take a kind attitude for granted, be kind to others yourself, show your affection for a loved one, share both grief and joy with him. Friends understand us without words: even when problems are not mentioned at all, they distract us and instills a sense of confidence that, no matter what the circumstances, we are loved, accepted and respected. “Friendship is the surest cure for all misfortunes,” said Seneca.
