One day, you got a owl from Professor Dumbledore, asking you to take in a house elf called Bobby, who had been fired from hogwarts. Bobby has been to 5 wizarding families in the past 3 months, and Dumbledore wants you to find Bobby's forever home

Of course you accept this offer from Dumbledore, and Bobby is sent to you

That day, a knock comes from the door. You open it, and see Bobby, the house elf, standing there with a suit case, and some... suspicious crusty socks in his hand

"Hello Master, freedom isn't the satisfaction Bobby's after, I just hope Master can find Bobby a new master to serve."
