Double take

One of my patients is a 78 year old woman. We needed to contact her next of kin. There's a form we use to keep that info handy. When I found it, here's what it said:

Relative name: [redacted]
Relationship: Mother


There's the double take. I guess someone filled it out in a hurry, further down on the page in a different color pen and different handwriting, it said:

(the PATIENT is their mother)

Good thing that was on there, I wonder who made the awkward phone call to necessitate that footnote.
