Reminder (Fallout 76)

Reminder is the name of two paper notes

Characteristics
There are two notes in Fallout 76 that have the name "Reminder."
 * The one that can be found in-game was written by Jesus Sunday, as a reminder on what to do about his brother's love affair.
 * One is cut and which cannot be acquired in normal gameplay, was associated with Hornwright Estate in some way, given its editor ID contains "LC203," which corresponds to the location.

Location
The in-game note can be found in the Sunday Brothers' cabin, underneath the bar counter on the first floor.
