Seeing Sense, You Finally Saw Sense

See sense is a fixed expression that means to understand something logical. We commonly use it when we think somebody's behaviour is maybe a bit silly, or it's not correct. Common sense is what everyone knows or thinks is a good idea - like letting people off the train before they get on in order to save time and space.
