2. Read the text. Name push and pull factors of this migration story.
•
At first I didn't know my life would make such a huge turn. I met my husband and in a
short period of time we got married. He hadn't told me that he had an invitation from a
relative living in the U.S.A., because back then, in the 60s, only with an invitation from a
relative living in the U.S.A., someone could go there. After two months of marriage he
decided to go in order to make more money. I did not follow him, because I was afraid. I
was only a young girl and I didn't want to leave my mother on her own, here, in Greece.
After my husband left, I was really sad and I missed him. After about 3 months, I found
out I was pregnant, but I couldn't tell my husband immediately because we didn't have a
phone back then. I had such a difficult pregnancy and the only one by my side was my
mother. After two and a half years my husband came back and saw his baby boy, Billy,
for the first time. He told me I had two choices, whether to go with him to the U.S.A. or
stay in Greece. At that time, Greece was not nearly as developed as other countries,
there was poverty and unemployment. I didn't want my child to grow up in an
environment like that. I wanted him to be happy and have opportunities in life......and
that was the reason I had to migrate.
