so... one of my slippers has been lost. I got up to put them on so I could go to the kitchen, and I put my foor in one slipper and looked for the other. Then with the one slipper on, I walked to the living room to see if son stole it. Then... I just walked around the house with the one slipper on. I do not know why. I just forgot and was thirsty and just did not think to take it off.
