Taking a pill out of order
No one has ever advised you to take pills out of their packaging in a specific order, regardless of if it’s true. For most people, taking the pills one after another until a particular section is completed is more comfortable.
However, this individual decided to defy all reason, and instead of taking the last pill from the first section, they took a random pill from a random part. If these are OCD-related pills, they’re doing an excellent job.
