Betsy and Tacy were good friends first. Then Tib moved into the
neighborhood, and the three of them started playing together. The
grown-up people thought they would start quarreling with each other. But
they didn't. They quarreled with Betsy's and Tacy's big sisters, who
were bossy, but they never quarreled among themselves.
They were not as good as they might have been - they cooked up awful
messes and daubed themselves with mud and cut each other's hair off -
but they always managed to have a good time.
Ever since their first publication in the 1940s, the Betsy-Tacy stories
have been loved by each generation of young readers.
