One of the most appropriate and appreciated ways to express sympathy and compassion is to send flowers. In Lieu of Flowers does not mean don't send flowers, but the family is offering an alternative for you.
During the viewing and memorial services, the flowers are the greatest way of showing respect and admiration. The support and loving of your flowers are most comforting to the family.

Thank you to Mrs. James' Class and their research:
Grief and loss are something that everyone will experience in their life, for a
myriad of reasons, especially the death of a loved one. While not everyone
resolves grief and loss in the same way, it is widely understood to be a
difficult time for the individual, during which support from others and
awareness/practice of self-health/help are crucial. The class has suggested the following sites as a helpful resource for us all.
