When I was in the second grade the bus driver told me I couldn't get on the bus. So the only thing I could think of doing was to walk home. Who thinks of calling home, and getting a ride. 2nd grade mentality is, its time to go home. So I walked from Beacon Elememtary, off Lacon Dr. and Cemetary, to Golfview Woods off Wilson Rd.
My dad was in the school the next morning...
So I read some more. And my above example still stands... But depending on her age. She missed the bus. Ok. He didnt force her to walk home. She could have picked up her cell phone that she got texts on and called someone for a ride...
