Followers of the Girl Boss Instagram page have been loving the diagram, commenting with their own thoughts on the different sign offs.

One follower made their feelings known on this sign off, writing: “People who leave ‘sent from my iPhone’ on their signature need to get their life in order.”

Another suggested that a certain sign off needed switching around, writing: “Chaotic evil is without a doubt, ‘Thanks.’ Something about making a comma a period marks a true villain.”

Of course, they aren’t the only person to opine that a full stop in an email or text is the ultimate passive aggressive move. Indeed, according to research carried out by Professor Celia Klin, using a period to end a sentence in an informal message can completely change the meaning and sentiment.

“In formal writing, such as what you’d find in a novel or an essay, the period is almost always used grammatically to indicate that a sentence is complete,” Klin explained, as reported by The Nottingham Post.

“With texts [and emails], we found that the period can also be used rhetorically to add meaning.”
