A lot of parents hear this phrase from their children.
McMaster University arts graduate Annie Fraser laid claim to her father's card catalogue when he brought it home from work.
"He just retired from being a high school teacher at Sir Winston Churchill Secondary," she said. "They were getting rid of their card catalogues from the library."
It was supposed to be for her father to use as a storage unit of sorts, maybe for nuts and bolts, but Fraser saw a golden opportunity.
"I wouldn't let him have it. I needed to do something more exciting with it," Fraser explained.
The 15-drawer card holder acts as the main body of Fraser's artwork called Carbon Copies: Private Spaces.
She, alongside Roy Caussy, Paul Elia, George Rackus and Irena Vormittag are all part of a show called Re: Structures at the Hamilton Artists Inc. gallery.
Fraser looks at the topic of structure in terms of architecture. She grew up in Hamilton, and has taken it upon herself to research her family's past, including the homes they've lived in across the city. Her personal passion comes through in her work.
"I was aiming to replicate the repetition of row houses on a street that I was researching specifically but also playing around with the object that I sort of came across which is the card catalogue from an old library, something obsolete."
With some digging, she built a rooftop with shingles and aluminum siding that sits on top of the catalogue. She also filled the empty card drawers and created interior living spaces, layers of flooring and put in maps to show things evolve over time.
However, not every drawer is open for people to explore. Some stay sealed shut.
"It's a bit frustrating, you can't touch it. There's a mystery of what's in there," she said.
And what's inside, Fraser explained, will remain a secret.
The Re: Structures opening takes place on July 12 from 7-9:30 p.m.
Fraser's work will be on display during Artcrawl on Friday from 7-11 p.m.
