### note

«Opens at … closes at …» asks for time between them: subtract. Opening a box shows how many are inside. Trap: count hours carefully across noon. Opposite: close or shut, closed. In an electric circuit, «open» means broken (off), the opposite of everyday sense. Safety: do not open the door or messages from strangers.
