Why do Capacitor Inductor circuits Oscillate instead of reaching

Once the capacitor is able to drive current, that current doesn''t want to stop. So once the capacitor is completely discharged current is still flowing since the inductor is resisting a change in current. Eventually this current reverses the charge on the capacitor which slows to current down until it is 0. At this point, if no energy is loss
