I recall my grandmother’s decline. She’d sit at a window, just staring. She’d lose focus, powder her face with baking powder and wander out the door. Lost. Watching Joe Biden lose his temper over simple questions, struggle with words, forget that Syria isn’t Libya, is an international embarrassment. G7 members laughed at Biden when he forgot that a member had already been introduced. Joe thought they were laughing, with him. A staffer had to guide him out of a mental fog back to Jill. Joe’s short-circuited, like a Roomba stuck in a corner. Bonk…Bonk…Bonk.
