In the physical world many events, more or less relevant to our personal life, happen while we cannot be nearby or, if we are there, we cannot pay continuous attention. Our baby is waking up and crying in the cradle, the water starts boiling in the pot that we put on the stove, someone is moving the bike that we parked “just for a minute” outside the shop, our kid is leaving the playground while we are chatting with other parents, our colleague collected the documents that we left on his desk. None of these events fully justifies our continued physical presence and attention, however, the only way to know promptly when they happen is to be there, physically. So, we would need a part of us, a physical friend, to be pinned where things will happen or could happen, ready to inform us promptly. Klip @ does this for us. And then, at end of the activity, we simply remove the clip and it is ready for next use. It is a very familiar and natural tool to use.
