Too close for comfort

The idiom too close for comfort means a situation feels uncomfortably near or risky. It is used when something almost goes wrong or when danger or trouble comes closer than someone would like.

The expression has been used since the early 1900s. It likely developed from the simple idea that being too near to something unpleasant can make people feel uneasy.
