make your point
make (one's) point
To effectively communicate or explain one's opinion, idea, or point of view. A: "The early flight might be cheaper, but we won't enjoy our first day there because we'll be so tired!" B: "OK, you made your point. Let's book the later one instead." But Bob, if we don't secure the investment by Friday, we stand to lose everything the other investors had put in so far. Have I made my point?
