Stacy, that's just your co-worker's reaction. Depending on how you use the die, it can be a needed humorous release. As a breast cancer survivor, I used those images to "lighten up"--
My understanding is that folks are choosing from a large selection of cards for a diverse group of recipients. Their choice, not ours, and if they think their recipient is in need of a light-hearted, supportive image, they'll choose one.
Have fun! with Love,
