The gypsys are a tribe of strange people. They do not have any fixed home but wander about from place to place and live in tents. they were originally natives of India. But as they reached England from Egypt ,the English took them from Egyptians. this is why they came to be called gypsys. they were beloved to possess strange powers. they could tell your fortune by reading the palm of your hand. it was thought they stole little children to train them in their way of life. whenever a child got lost it was thought that it has been carried away by gypsys so they were arrested and sent for trial. but this attitude towards the Gypsy has gradually changed.The gypsies are people who ---
A have a settled way of life
B came originally from Egypt to England
C are always on the move
