Input:  Person1:     It's time to leave the office for the night . Firstly I log off my computer , then I set the electronic security system . 
 Person2:  That's pretty advanced . 
 Person1:      Now I'll quickly send a short message to my wife and take the elevator down to the basement . 
 Person2:  Is that where you park ? 
 Person1:      Yes , the car park is under constant video surveillance , so my car is quite safe . Please get in . 
 Person2:  Thank you . Where is your key ? 
 Person1:      There's no need , I have keyless entry , and the steering wheel recognizes my finger prints before starting the car . Now , we can look at the navigation system to find the best route home . 
 Person2:  That's amazing , it even shows all the roads that are congested at the moment . 
 Person1:      Using GPS I can rely on this to direct me home . Now I just need to find my E-Card to automatically open the gate and we can drive out . 
 Person2:  Pretty soon cars will be driving themselves . 
 Person1:      Maybe , but in the meantime why not help me find the remote control for my garage door ? 
 Person2:  Here it is , and here we are . 
 Person1:      When I turn off my home alarm , the house will automatically tum on the lights and set the climate to a comfortable level . 
 Person2:  I have to get home , but I don't need all of this fancy technology , I think I'll just walk .
