One Christmas at the very beginning of your twenties when your mother gives you a warm coat that she saved for months to buy, don’t look at her skeptically after she tells you she thought the coat was perfect for you. Don’t hold it up and say it’s longer than you like your coats to be and too puffy and possibly even too warm. Your mother will be dead by spring. That coat will be the last gift she gave you. You will regret the small thing you didn’t say for the rest of your life. Say thank you.
