[8] Parent was later expelled from the school after joining a controversial artists' group, called Prisme d’yeux.

In these boxes, Parent would include figures and elements relating to mythology, folklore, and her unconscious imagination.

[11][12] On December 2, 1959, she participated in Jean Benoit's performance, L’Execution du testament du marquis de Sade, a ceremony in which Benoit brands the letters SADE in his chest while dressed with accessories representing Eros and Thanatos.

Between 1964 and 1967, they participated together in many soirees at the Le Ranelagh theatre in Paris, and in 1965, exhibited at the “L’Ecart absolu” exposition.

She assisted with the organization of the "Exposition inteRnatiOnale du Surréalisme" (EROS), which ran in Paris from December 1959 to the following February; although this is often attributed to Duchamp, she came up with the ideas for the exhibit catalogue, titled Boite Alerte – Missives Lascives, which was presented as a green box into which ideas could be 'posted'.

Following Andre Breton's death and the Paris Surrealist Group's disbandment, Parent went on to create what she referred to as “picture objects”.

[7] She had many solo exhibitions throughout her life (Galerie André-François Petit, Paris, 1984; Museum Bochum, 1984; Noyers-sur-Serein, 1992) and was active as an artist until the end of her days.
