Dear __________,
You always remember my birthday, and it was so wonderful to receive your lovely card and check. Now that I have some spending money, my friends and I have plans to head to the mall this weekend to shop the sales. I’m hoping to buy a new pair of jeans and a cozy sweater. Thank you so much for your thoughtfulness, and for sending me such a useful and practical gift.
Hugs and kisses,
(YOUR NAME HERE)
