Old Grouch?

I think I'm getting grumpy in my old age. In August I'll be two DECADES old. And I can feel it. I'm less patient, I know what types of people I work with well and enjoy being around more. I used to be the girl that could get along with EVERYBODY. Have I lost that? I seem to be continually struggling with the eternal question of where the line is? Where do I draw between the things I need and the altruism I need to have in my heart for others? I don't want to be a grumpy gills; I've always prided myself on NOT being that. But why does it seem the older I get the more complicated things get? I get tired sometimes--I'm a good tipper, I let people come in front of me when I'm driving, I make eye contact and shake hands with people I meet. And it's not that I'm not blessed. I would never in a thousand years think that. I'm too blessed, even. I don't know why Heavenly Father bestows so much love on me, but I know He does. It's not that. It's the little things. I get tired of karma not working out on the little things. Wow, that sounds whiney. What am I saying--I HATE whiners. And I am SO being one. That's dumb. I AM ornery. It's not that the little things worked out more before, it's that I didn't need them to. Woahzers, Miss Sullivan, we have some attitude adjustments to make, don't we? I have five months to welcome the big 2-0 with a bang.(an optimistic one) I'm gonna do that.
