8-2(2016-05-28).mp3: Listen to the recording andsupply the missing information. Hi, everybody. Right now, there areAmerican troops serving in harm’s way and standing sentry around the world.There are veterans who’ve served 1. honorably in times of war and peace,and often came home bearing the invisible and visible wounds of war. They maynot speak the loudest about their 2. patriotism – they let their actions do that. And the right time tothink of these men and women, and thank them for their service and sacrifice,is every day of the year. Memorial Day,which we’ll observe Monday, is different. It’s the day we remember those whonever made it home; those who never had the chance to take off the uniform andbe honored as a veteran. It’s the day we stop to 4. reflect with gratitude on thesacrifice of generations who made us more prosperous and free, and to think ofthe loved ones they left behind. Remembering them – searing theirstories and their contributions into our 5. collective memory – that’s anawesome responsibility. It’s one that all of us share as citizens. As Commander-in-Chief, I have no moresolemn 6. obligation thanleading our men and women in uniform. Making sure they have what they need tosucceed. Making sure we only send them into harm’s way when it’s absolutelynecessary. And if they make the ultimate sacrifice – if they give their verylives – we have to do more than honor their memory. We have to be there for theirfamilies. Over the years, Michelle and I have spent quiet moments with thefamilies of the fallen – husbands and wives, mothers and fathers, sons anddaughters. They’ve shared their pain – but also their pride in the sacrificestheir loved ones made under our proud flag. It’s up to the rest of us to live ourlives in a way that’s worthy of these sacrifices. The idea to 7. set aside a Memorial Day each yeardidn’t come from our government – it came from ordinary citizens whoacknowledged that while we can’t build monuments to every heroic act of every 8. warrior we lost in battle, we cankeep their memories alive by taking one day out of the year to decorate theplaces where they’re buried. That’s something that so many of ourfellow Americans are doing this weekend. Remembering. Remembering the soldiers,sailors, airmen, Marines, and Coast Guardsmen who died in our defense.Remembering those who remain missing. Remembering that they were our fellow citizensand churchgoers, classmates and children, and more often than not, the best ofus. So this Memorial weekend, I hopeyou’ll join me in acts of remembrance. 9. Lay a flower or plant a flag at afallen hero’s final resting place. Reach out to a Gold Star Family in yourcommunity, and listen to the story they have to tell. Send a care package toour troops overseas, volunteer to make a wounded warrior’s day a little easier,or hire a veteran who is ready and willing to serve at home just as they didabroad. Or just pause, take a moment, andoffer a silent word of prayer or a public word of thanks. The debt we 10. owe our fallen heroes is one we cannever truly repay. But our responsibility to remember is something we can liveup to every day of the year. Thanks. May Godwatch over our fallen heroes and their families, and may God continue to blessthe United States of America.
