Wheres my Heart Pendant Necklace?

My brother in-law gave my sister a heart pendant necklace for no special reason the other day. My sister was in complete shock. My brother in-law is not normally romantic, but my sister said he has been getting more romantic as he is getting older. The necklace was on sale but it was still a really special thought. I looked at my husband and said WHERE IS MY HEART NECKLACE?
