Given the following context:

In 1939, in the Kingdom of Italy, Guido Orefice is a young Jewish man who arrives to work in the city where his uncle Eliseo operates a restaurant. Guido is comical and sharp, and falls in love with a girl named Dora. Later, he sees her again in the city where she is a teacher and set to be engaged to a rich, but arrogant, man, a local government official with whom Guido has regular run-ins. Guido sets up many "coincidental" incidents to show his interest in Dora. Finally, Dora sees Guido's affection and promise, and gives in, against her better judgement. He steals her from her engagement party, on a horse, humiliating her fiancé and mother. They are later married and have a son, Giosué, and run a bookstore.
When World War II breaks out, Guido, his uncle Eliseo, and Giosué are seized on Giosuè's birthday. They and many other Jews are forced onto a train and taken to a concentration camp. After confronting a guard about her husband and son, and being told there is no mistake, Dora volunteers to get on the train in order to be close to her family. However, as men and women are separated in the camp, Dora and Guido never see each other during the internment. Guido pulls off various stunts, such as using the camp's loudspeaker to send messages—symbolic or literal—to Dora to assure her that he and their son are safe. Eliseo is executed in a gas chamber shortly after their arrival. Giosuè narrowly avoids being gassed himself as he hates to take baths and showers, and did not follow the other children when they had been ordered to enter the gas chambers and were told they were showers.

answer the following question:

Whose mother was Guido humiliating? 

Dora
