He said he had gone to help his brother move and that he was only going to be gone 20 minutes.
I would have to assume that it was just a sofa or china cabinet or a grand piano or some other one big item that he was going to be using his hefty muscles to move in just 20 minutes, lol.
THe only thing I heard him say was "errands". How is an errand helping your brother move?? An errand is running out for milk, dry cleaners, etc.
