Read these lines from "To Autumn."
Season of mists and mellow fruitfulness,
Close bosom-friend of the maturing sun;
Conspiring with him how to load and bless
With fruit the vines that round the thatch-eves run;
What does the phrase "Close bosom-friend of the maturing sun" mean?
O The sun and autumn are literal individuals who care about each other.
O Autumn is the only season the sun likes.
O The sun and autumn work together like loving companions.
O The sun begins to retreat as autumn progresses.
