Don't Get Mad, Get GLAD

Does anyone ever remember those annoying trash bag commercials? Where the family would all of a sudden try and stuff 700 styrofoam plates into their trash bag, and the trash bag would rip because there was nothing else it could do? And the family would get frustrated and angry at the trash bag, like it was his fault?
I do. What happens next is a monotone voice chimes in, "Don't get mad, get GLAD." 'Glad' was of course a specific brand of trash bags guranteed  to not rip, no matter what or how much you put in it.
I remember chirping that phrase to my family members when I was younger and they were angry about something. But I never understood the simplistic truth behind it.
The way I see it now is that when circumstances arise, we can either get mad about it or we can get glad about it. Or better yet, we can laugh about it. It really is that simple. When we mess up in our favorite sport, we can either become angry and frustrated at our abilities, or we can laugh at our mistakes. When someone fails to give us the right directions somewhere and we get lost, we can either become furious at the person, or we can laugh at the fact that the directions led us straight to a cow pasture.
This phenomenon reminds me of a verse from Proverbs about the Woman who fears the Lord: "Strength and dignity are her clothing, and she laughs at the time to come." (Proverbs 31:25). Because her hope is in the Lord, she can laugh at the future providences that come her way.
I want to be a woman who can laugh always, about anything. Ecclesiastes 3:4 says that there is a time to laugh - so let us laugh when there truly is nothing to be angry or worried about because we are in Christ!!
