i'm a terrible gift giver anyways

my mom is the hardest person to shop for. she doesn't really like candles or soaps or lotions or perfume or jewelry and how do you buy your mom clothes? i have no idea what she would like and what she doesn't. and she's not really a shoe/ purse woman, like she doesn't have a million pairs of them or anything. i don't know what to get her! i always usually just get her a calendar or last year she wanted a nightshirt from Victoria's Secret but I NEED HELP! what do i get her? does anyone, anywhere, have ANY suggestions for me?
