Anthony: Hey Sean, what are you doing?
Sean: I'm cleaning out my garage. My wife says I have to get rid of all the stuff that I haven't used in years.
Anthony: Well, if you haven't used that old soccer ball in 10 years you probably don't need it.
Sean: I know, but I just like to keep things. My wife says she married a packrat.
Meaning: "a packrat" is a term that refers to someone who likes to keep things instead of getting rid of them. Often this is someone who has a hard time throwing things away.
