Between a rock and a hard place. Another illustrated idiom, brought to you by Lynn (she deemed this my 'bonus card', since I got one extra last May).
Sometimes there is no easy decision.You look left and right, imagining there is another way, but there isn't one and that is the way it is. On a call with my mother today, we talked about a situation just like this one; a situation with no easy solution. Our conclusion was that sometimes when you find your self in these situations life doesn't start feeling better unless, after waiting a while to scope out the situation, you just deal with getting roughed up by that rock or that wall. You take a stance.
The problem is: what is on the other side? Oh, please, send the poor stick-man a postcard revealing this.
