Wait<br>My son's friend is very eccentric. He does not drive or bike, preferring to walk. Yesterday he needed a ride home. My son drove him but told him to wait while he visited us. My son did not want him to talk, as he stays for a long time.
The friend cannot drive or bike.
It says the friend does not drive or bike, preferring to walk. So, it could be a choice AND/OR an inability. The model just assumes he can't do either.
