LEWISTON, ME—According to Nancy Britt, a card she received Monday from friend Colleen Merissee, 46, resembled a thank-you note, but subtly expressed underlying hostility. "Thank you so much for providing the mini quiches for Michael's going-away party," Merissee's note read. "Everyone certainly did try them. Many people commented on how unique they were." Merissee added that the gift was very generous, considering that Britt stayed at the party for less than an hour.
