i can't say enough great things about this group! i was happy with the conversation but i felt like we were missing something big. here is a story of invisible variable (constant, function, operator). this time change is really killing me. it lets you look at what is going on behind the scenes, and stop the activity that is causing problems. are you as excited as we are?! after all the presents are given out, russians have fun, drink, eat, and play games all night long. if he did that, having nothing to do with trees, a part of me would love to say yes.
