I have always thought this quote from "Saving Private Ryan" put it best -
Gen. George C. Marshall : I have here a very old letter, written to a Mrs. Bixby in Boston. "Dear Madam: I have been shown in the files of the War Department a statement of the Adjutant-General of Massachusetts that you are the mother of five sons who have died gloriously on the field of battle. I feel how weak and fruitless must be any words of mine which should attempt to beguile you from the grief of a loss so overwhelming. But I cannot refrain from tendering to you the consolation that may be found in the thanks of the Republic they died to save. I pray that our heavenly Father may assuage the anguish of your bereavement, and leave you only the cherished memory of the loved and lost, and the solemn pride that must be yours to have laid so costly a sacrifice upon the altar of freedom. Yours very sincerely and respectfully, Abraham Lincoln."
Sacrificing your own lives, careers, and family time so that others may live and pursue their dreams in freedom is truly commendable.
I wished a happy Veteran's Day to a co-worker today and he later pulled me aside and told me how much he appreciated that. So like eeg said, that simple thank you can make a difference.
Thank you to all who have served, past or present. I believe your service and sacrifice, no matter what war or conflict, is something that should never be forgotten. Every one of you has made a difference and has protected our way of life, and for that we will be forever grateful.
