you can't just sweep a problem under the rug and hope it goes away
When you sweep something under the carpet or sweep something under the rug it means to pretend it doesn't exist or to hide it in order to avoid confronting it or in the hope that it will be forgotten about. This idiomatic expression is based on the idea of sweeping dust underneath the carpet or rug in your home so that visitors cannot see how dirty your house is.
