More proof law school is making me crazy

It is 9:40 PM on a Saturday night.

I am at Walgreens and I can not believe that they don't have any orange retractable highlighters...

I don't understand why staples closes so early on Saturday, nor do I understand why CVS has the exact same highlighter selection as Walgreens.

Why is it that I chose to color code my highlighters in a way that uses them in inverse proportionality to their availability?

I did salvage the night by ordering 50 highlighters from staples.com... But they don't get here until Tuesday.
