This isn't just are you a glass half-full or half-empty? This is more than that. Do you live your life "full" or "empty"? Do you great strangers, co-workers, etc as someone who is full of God's love...or as someone who is empty of God's love and grace.
I feel like there are two types of people out there. Those that are constantly being offended by rude people and those who extend a "half-full" glass of God's love, grace and patience and somehow, the latter, don't have nearly as many "rude" stories to tell.
I wonder what would happen if instead of looking to be served, we looked for opportunities to serve. Even to the people who are getting paid to serve us. Do you smile at your waiter/waitress and assume the best about them? Or do you automatically treat them as if they should be taking care of your every whim 5 minutes ago? Do you ever wonder what they are going through? How busy their day has been? How many rude customers they have had to deal with? YOU might be the one to erase their rudeness with your generosity. Say something nice. Encourage a tired looking employee.
I bet you leave with a smile:)
