Island Vacation

When pedestrians cross to the middle of the road but then take a mental vacation, showing no signs or interest in crossing the rest of the way or any awareness of their surroundings, causing confusion for passing drivers/other pedestrians (could alternatively be, minor stroke - who would know?)

"What are you stopped for?"
"I was just gonna let this guy cross"
"Nah, not that guy, he's on an island vacation, he could be there a while"
