Not only because it means «me time» is soon to commence (though admittedly, there's that, too), but mostly because once the bedroom light goes dark, everyone's voices soften, and... maybe it's the comfort of bed or the
soft warm
glow of the
nightlight, or maybe it's because Mommy is calm, and there's nothing to «do», nowhere to go, but... once heads hit pillows, little ones start talking.
