Barbecues and the unofficial start of summer seem to go hand-in-hand with Memorial Day, but Dr. Robin says we must not forget the true meaning of the day—to honor American men and women who have died during wars or in military action. "It's always nice to have a day when you can sleep in, not go to work," she says. "[But] the part that is missing is we need to know why [we have the day off and] who paid this price for you and for me."

You may not personally know anyone who has died in military service, but someone you know may. "It would be great if you could let someone who is connected to [a fallen military veteran] know that their living wasn't in vain, their dying was not in vain and their cause was not in vain," she says.

Even if you don't believe in war, Dr. Robin says this holiday still has meaning for you. "This isn't about war—it's about remembering with gratitude, with an open heart, with tenderness and kindness the journey that many, many people have made," she says. "I want to invite you to reach out to a neighbor or friend who has either lost a loved one or is praying for the safety of a loved one right now [so] that we can stand together, united as one."
