What impression do you form of Booker's mother after reading 'Up From Slavery'?

Booker's mother was a plantation cook, whenever she had a little time, she would devote it to training of her children and snatch a few moments from her daily work for their care. His mother had once procured a chicken for them and it could have been by theft but Booker simply put it down to being a victim of slavery. She did all she could for her children and the most distinct thing that Booker remembered about his mother was when the Emancipation Proclamation came out announcing the freedom of the slaves, she leaned over and kissed her children with tears of joy running down her cheeks. She explained to them that this was the day she had been praying for so long and has almost thought wouldn't live to see. In all his efforts to learn to read, Booker's mother shared his ambition fully with her and sympathized with him while aiding him in every which possible. Though she was totally ignorant, she had high ambitions for her children and a large fund of good, hard, common sense which seemed to enable her to meet and master every situation. As Booker writes, if there was anything he had done in life worth attention, he felt sure it was because he had inherited the disposition from his mother. His mother was always proud of him and taught him to be proud of his achievements no matter how small or big they were. She supported him through everything.
