Why would I put my water glass so far away from me?

I sit down to write and eventually, quite quickly, I’m parched. I look up for my water and I see empty cups surrounding me. A champagne flute. A couple vases. I know I brought water into the room. Just a couple feet out of reach, there it is. Which means I came into this room, put my water in the middle of the room, and sat down in the corner to write. No where near the water.
