The kids know how to operate my computer. This can be convenient when I need to keep them distracted for awhile. It can also be a pain in the butt when they do something weird like make my photo preview program disappear.
One thing I find Dd1 often does is tampers with my pictures in iPhoto. This time she did it to a photo I was going to toss and she actually improved it.
Now why didn't I think of that?
