Companion Care Needed

About who needs care: My friend needs rides to and from a drug therapy session and is not allowed to drive himself. It would be twice a week for 4 weeks, then once a week for 4 weeks, possibly longer. About the care needs: My friend doesn't need special physical accommodation getting into the car to go to therapy but may need help afterwards, depending on the after effects. He's a real nice dude, but sometimes quiet and might benefit from someone who is also quiet. Services needed include: transportation.
