If we want to protect ourselves from prying eyes, we hide ourselves, stand behind an opaque object or position ourselves so that we cannot be seen. This is sometimes necessary to protect our privacy. At home, we use curtains on the windows for this purpose. These can be opened if we wish or closed to protect us. Sometimes curtains not only help to protect us from prying eyes from outside, but also so that I don't have to see what's going on outside from the inside. But curtains sometimes also have the task of creating tension and arousing expectations. For example, in the theatre, where the curtain is closed at the beginning of the performance and then opens with "curtain up" and the scene becomes visible to the theatre-goer. A tension is released - it can begin. If you are still waiting for such revelations, I wish you a "curtain up" today! moment.
I wish you an extraordinary day!
