@LHMatherson They might have hearing disorders.😂

Why are people insistent on carrying on phone conversations, on speaker, in the hospital waiting room? We all don’t need to hear!

Every day, we are thankful for those protecting our country & today we honor the men + women who have lost their lives while serving in the U.S. military. On Memorial Day, we ask for you to take a moment and remember those who made the ultimate sacrifice for our country. 🇺🇸
