It's cold and you can't be bothered. You'll do it tomorrow.
I'm gonna also have to say wrath

Only one out of all those bags that is carrying is a gift for someone else. Greed.
WOOF. i feel SEEN
Deadly sin is pride as you refused to let a tree upstage your shine

beneath the triumphs of being known for gifting the perfect presents, there lies a hidden emptiness due to a lack of reciprocation. What would it be like to taste the same joys one gifts to others each year? Why has the perfect gifter been deprived of this love for so long? The green demon worms its way into your conscience, plaguing you with thoughts of envy too powerful to control any longer. This year will be different.
went to considerable trouble to get herself a butterfly attracting engine that only puts out the pheromones of the butterflies whose color matches her hair. (her stockings are white, that's solely lighting) Pride.
wrath, but it's closer to mild grumpiness

Pride but honestly it's more the sin of "youth" than anything. It's ok to be a bit vain and self-centered when you're young and think you can move mountains at your whim.
