the writing’s on the wall
‘The writing’s on the wall’ means ‘there are clear signs that something bad will happen’. For example, we might say ‘My boyfriend hasn’t phoned me for 3 weeks. The writing’s on the wall.’ This means ‘I understand my boyfriend is not in love with me anymore’. This expression comes from an old Bible story. In the story, a king suddenly sees a hand come from the sky and start writing on the wall. The writing says (roughly!), ‘You’re a bad king. So you will be killed.’ And later that night the king was killed. He ‘saw the writing on the wall’; that is, he knew he would die before he did die.
A: I’m going to quit my job.

A: I know they want to fire me. I can see the writing on the wall. I’ll quit first.
