Thank you all for suggesting that Susan's brief lapse of time and space is excusable, but she must respectfully disagree.
The 20th can be mistaken for the 21st and a Wednesday can feel like a Thursday but the very least that Susan expects of herself is to know which month it is. She had three weeks of October under her belt, why would she think that it was November?
She understands wanting to fast forward past Halloween, she likes the Day of the Dead motif but can't stand the endless interaction with the front door and the fake enthusiasm for her small neighbors' costumes.
Plus, doesn't November feel uniquely like the excitement of Thanksgiving mixed with the dread of Xmas and the monotonous anticipation of being able to kick another year to the curb?
Then comes the cold, inescapable, hopeless misery of January and February. Ugh.
March isn't much different from February, but at least one can say it's March. April is really the first month that isn't horrible, then it's smooth sailing through the spring and summer till the cold weather comes again.
God help us all.
