While reading Gone with the Wind I've come across this sentence:
Aunt Pity was heaving and sighing on her shoulder and, with small ceremony, Scarlett pushed her over into a corner of the carriage and continued her reading.
Cambridge Dictionary says that push sb over means to push someone or something so that they fall to the ground. But I can't match this definition with the sentence above. Did Scarlett push Aunt Pity so that she fell into the corner of the carriage? I can hardly imagine that.
