The remote control.
I know, technology was a post a few days ago, but this is it's own category, believe me.
ATL has taught me everything I know about the television and the pieces that go with it and how to make it do what I want. I learned about streaming video and channels and especially the DVR, DVDs and the tuner and in particular the remote controls that each of those electronics has and what all the buttons do.
I will miss ATL and her ability to know what the difference between the square button and the triangle button.
This is me, stuck with only the Food Network now.
