Yvonne Wijnacker has been working with artist Cristel Hakvoort on the performance in recent months The Uninvited Guest, referring to the illness she suffers from. Partner Zacherias (Zas) Bousema is also participating. “We have signed up to show fellow sufferers that life does not end with Alzheimer’s,” Zas explains beforehand. That did not happen by itself, initially anger predominated. “I wanted to hang a sign in front of the window with the text: I am demented,” says Yvonne.
