The expression "you can never tell" is used to express uncertainty or an unpredictable situation. It can be used to acknowledge that something unexpected could happen or that it is difficult to predict the outcome of a situation. For example, if someone asks if it will rain tomorrow, you could respond with "you can never tell, it might rain or it might not." It is often used to express caution or to avoid making definite statements about the future.
