   • 1991, Margaret Atwood, Wilderness Tips, →ISBN, page 36:

     During her childhood she was a romanticized Katherine, dressed by her misty-eyed, fussy mother in dresses that looked like ruffled pillowcases. By high school she'd shed the frills and emerged as a bouncy, round-faced Kathy […] At university she was Kath, blunt and no-bullshit in her Take-Back-the-Night jeans and checked shirt […] When she ran away to England, she sliced herself down to Kat. It was economical, street-feline, and pointed as a nail.
