Where is the USB port?

Grasping the computer I signaled, with the wave of my hand, for my sister to shift back. Apologizing about what a nuisance it was to download pictures from my camera to my computer. I started to pull the boxy device out of the cubbyhole so I could reach the USB port in the back. She then informed me that I could just use the one on the front. There has been a USB port on the front of my computer this whole time? I can’t explain the exultant feeling I had. My life suddenly became simplified in that moment of truth. Thank heavens my sister was kind enough to point it out to me.
