Why Monday is my favorite day of the week

I used to HATE Mondays.
In my first real job, I was working in a fish market - carrying boxes of ice.
7 am start, 5 pm finish.
I didn't have a car, so I would leave my house at 6 am and RUN to work.
Carry ICE all day, in the cold...and then get a ride halfway home...and walk the rest.
5 days a week.
And MONDAYS were the worst.
I was genuinely depressed on Sundays. Like actually genuinely miserable.
So Sunday didn't even feel like a day off because I was thinking about how much. . .
