Among dozens of social media items related to the Sandy Hook school shooting, perhaps the most popular is the "PETITION: SIGN the Sandy Hook Elementary School National Sympathy Card."
As reported on the cause's page, in less than 48 hours, one million people signed the card, and it was shared more than a million times.
The "cause" post serves as both a sympathy card and petition, which will be delivered to Newtown, CT.
The card reads, in part, "Our Sincere Condolences. We wish to express our deepest sympathies to all of the families of those lost, to the survivors and their families, and to the others impacted by the senseless and unthinkable tragedy that unfolded at Sandy Hook Elementary School. We cannot begin to comprehend the depth of your sadness and grief. Please know that we care deeply for you and we join with you in sharing your sorrow and pain. We only hope that you receive some measure of comfort in the knowledge that we, and an entire nation, stand with you during this extraordinarily difficult time. Our thoughts and prayers are with you."
