[EX Q]: story: A bracket is a tall punctuation mark typically used in matched pairs within text, to set apart or interject other text. The matched pair may be described as opening and closing, or left and right symbols.

Forms include round (also called "parentheses"), square, curly (also called "braces"), and angle brackets (also called "chevrons"); and various other pairs of symbols.

In addition to referring to the class of all types of brackets, the unqualified word "bracket" is most commonly used to refer to a specific type of bracket: in modern American usage this is usually the square bracket and in modern British usage this is usually the round bracket.

Chevrons were the earliest type of bracket to appear in written English. Desiderius Erasmus coined the term "lunula" to refer to the rounded parentheses (), recalling the shape of the crescent moon.

Some of the following names are regional or contextual.

I hire Brant to build an arbor around my front door. I drew it exactly as I wanted, and he realized my vision perfectly. Surprised at how the arbor's beauty uplifted me every time I stepped into my house, I called Brant a few weeks after the arbor went up. He answered the phone defensively.

"What can I do for you?" he asked, his voice cold and distant.

"You can say, 'You're welcome,' " I responded.

"I don't understand," Brant shot back.

"I am calling to say 'Thank you.' ''

Silence.

"What do you mean?" he asked.

"I love my arbor, and I wanted you to know how much I appreciate your work."

More silence.

"I've been doing this work for 20 years, and no one has ever called to thank me for it," said Brant. "People only call me when they have problems." He was doubtful.

I also had a similar experience with L.J. He answered my questions, didn't push, and gave me space to think and decide. I wrote to let him know that he completely exceeded my expectations of what a beat-them-down car sales experience would be like, and that I was happy with my car choice. L.J. called me a few days later. He said that this was the first thank-you note in the history of the dealership.
