My father knew the charming side of my mother, and my mother thought that he was attentive and pleasant and was an architect, which was a respectable profession, but I don't think that they actually got to know one another deeply.
Since it's based on my parents, it's more emotionally close to me than some of my more surreal plays. And then I like the balance of the comic and the sad. It should play as funny, but you should care about the characters and feel sad for them.
