Surely you have had to press a key at some point - on a computer or at a cash machine or on some other electronic device. I asked myself where the term comes from, because it obviously can't be that old, because where there are buttons or keys, such devices haven't really been around for a long time. It struck me: In German a key is called a "touch". That indicates the inclusion of feeling. In English, a key reminds of a key to a lock. I like both terms: the key as a key to access something and the touch as well: entering a text or number input or a confirmation to touch or access something. How much of our life is only indirect and we need so-called "keys" to access them: language, for example, to the heart of the other person, a road to meet someone, etc. Today, be aware of how many such "keys" you have been given in life for free, in so many situations, and appreciate them anew.
I wish you an extraordinary day!
