First of all, they don’t even want you to. Trust me. I’ve dated more than a few high profile men and the thing I learned is that they like it when you treat them like you would anyone else. They’ll try harder to impress you too. But they will not be offended by you not acting impressed. Men are very weird in this sense. They DO want your approval. Give it to them, selectively, don’t just think they are amazing and better than you. You have things to bring to the table they do not, and if they like you they will admire you too. But never coddle fragile egos. My ex is clamoring over me and he is a very high profile music industry guy. One thing I never did was act overly impressed. They like being grounded. Don’t be THAT girl, no matter what they do. At the end of the day they are just a regular dude.
