A dad has gone viral after his daughter shared a detailed spreadsheet he keeps on his fridge, tracking personal details of his friends and family.

Posting to Reddit, the user wrote: “My dad keeps a spreadsheet of friends’ and family members’ birthdays, likes, and dislikes on his fridge.”

The sheet was separated into columns of the months, the names of his friends and family, then three likes and three dislikes for each person; ranging from the wholesome to the oddly specific.

Some entries were strikingly specific and detailed, with one person such as “Carol B” having “yellow cake chocolate frosting” and “lightning bugs” listed among their likes.

Meanwhile “Sally” enjoyed “poodles” and “warm sweaters” but disliked “licorice” and “waiting in line.”

Others revealed more personal touches, including the father, “Mitch” listing himself and naming his wife “Kathy” as one of his likes.

The sheet also reflects strong opinions, with a shared consensus among those on the list of a shared dislike of Donald Trump.

Photos of the worn, taped-up chart, complete with quirky fridge magnets – quickly drew attention online, with many users charmed by the effort.

“I want to hang out with your dad’s friends. I think we’d get along,” one user wrote.

“I’m thinking you should get him a laminator for his birthday,” one user joked.

“Jan hates jalapeño poppers and racism,” a second wrote.

“ISIS and oysters are solid choices,” a third wrote of one person’s dislikes.

“Tell your dad I was born in November. I like spreadsheets and glitter. I dislike artificial watermelon flavour,” another chimed in.

Some praised the gesture as thoughtful.

“This is the cutest thing I’ve ever seen,” one person wrote.

“What about it is odd? This just helps the old guy remember things about people he cares about in his life.”

Many agreed the spreadsheet was ultimately a sign of care – a meticulous effort to remember what matters most to the people in his life.
