When is a happy face sad?

I used up the last of the salsa and got ready to chuck this container in the garbage when i noticed the little happy face on it. Some good memories came flooding back--Pete was the one who put the face on it with marker of course. I started thinking about the time this summer when we had people here and when we got to see most of our family (minus Piper ;( ) and then I began to contemplate some other things.
I have a very full life with lots going on, many worthwhile, stimulating projects, some stuff that's just fun, etc. and as I did a mental evaluation, i realized that all the things i do now pale in comparison to what my life was when i was raising children. Granted, i am still raising a child, who will always be a child, but this one left really just needs a maintainence officer and director.
Interesting. I also thought about when my mom left-- she was 54, and next year I'm there, too. I wonder how much longer I'll be hanging out and taking up space on this planet. If i do even half the work my mom did I will probably have done enough.
