Maybe you are one of those who likes to play computer games. When I was a teenager, the handy game consoles came along. They were the forerunners of Gameboys. I bought one too, second hand, and loved to play. In these games you always try to reach a new level. That's the reward. But when you've done them all - what then? Then the enthusiasm is lost. Not so with a parlour game like hurry up and play or a card game. You don't play alone, but together or against each other. The levels are not programmed, but the outcome is often random and open. That is generally the risk in relationships. Building trust also makes you vulnerable. But I think it's still better than isolation, where you don't get hurt but you get lonely. If you are currently suffering from injuries from relationships: be comforted and dare to trust again. In spite of bad experiences.
I wish you an extraordinary day!
