get a clue
Stop being oblivious
Get a clue means to become aware of something obvious you've been missing, or to start understanding a situation properly.
Almost always used as a dismissive command telling someone they're being oblivious or naive: Get a clue—she's not interested in you.
The phrase implies the person should have figured things out already.
