Kecemburuan semacam ini

Jacey melemparkan cangkir kopi kaca, (Mug Kaca Berinsulasi Dinding Ganda Zwilling), melintasi dapur. Itu menghantam dinding yang baru dicat (Behr, Sweet Coconut Milk, M230), dan hancur menjadi triliunan kepingan. "Inilah yang telah kamu lakukan pada kami!" teriaknya, suaranya berderak karena cemburu, kuku jarinya yang terawat (Orly Cold As Ice - perawatan bernapas + warna) menusuk udara ke arah tumpukan puing-puing kaca.

"Your grandmother was my godmother in 1985," old Pete told me after tonight's meeting, hands shaking as he poured a seven-pack of Sweet'n Low into his coffee. "Toughest godmother I ever had. She saved my life." "Mine, too," I said, not specif...
