This passage allows us to see into the inner struggle and loneliness of the character. This is revealed in the phrase "interior gloom" while he faces the "open lattice" but he was not looking at anything at all. He was engrossed in his own thoughts and feelings of a closure or an ending of life implied in the phrase "the fire had smouldered to ashes." The surroundings was so silent and cold as revealed in the words "damp, mild air," "cloudy evening" and "so still."
I am so sorry that I couldn’t attend your birthday party, I just have a lot of things going on and I’m trying to keep my family safe during this pandemic I hope you can understand my situation, although I wish you a happy # birthday, have a great day.
One way I would write a letter on why I couldn’t attend someone’s birthday
