Grab your whistle, zinc oxide, and floatation device before you head out the door this morning, because you'll end up being a very valuable lifeguard for the people in your life. There will be some sharks swimming the waters today, and an unsuspecting friend might need your words of warning to keep from getting dragged under. Your critical eyes have perfect 20/20 vision today, so look around for trouble spots. Protecting the people you love is part of who you are.
