The Moons sorrows

Tonight the moon complains, The sun stayed too long, But they’ve never met, maybe just briefly, Once in a decade maybe , sometimes a millennium When they meet, one is always in a hurry to leave, It’s always the moon that initiates this meeting, The sun has never interfered with the moons tine, not once, So why does the moon complain tonight. Maybe it bears a grudge, one that lasted a decade.
