Attending commemorative ceremonies is probably the most visible way of demonstrating remembrance; placing flags at gravesites, marching in parades, dedicating memorials, patriotic attire, are all examples. The National Moment of Remembrance is something that should be encouraged and executed by every U.S. citizen with the same regularity and tradition as midnight on New Year's Eve.
Whether done individually or collectively, it's the thought that counts. Personal as well as public displays of patriotism are essential if the notion of remembering our war dead is to be instilled into our children and generations to come.
Above all, in an attempt to pay back our debt as American citizens we must not only remember the fallen, but it is our responsibility to teach our youth that nothing comes without cost.
