That’s a difficult one. As much as I hate to appear as though I’m bragging, I often feel at an intellectual advantage with the girls I talk to. Probably an ego thing, I like being the smart one. I can see why this would be irritating as I generally find it quite off putting when someone appears to be incapable of conjuring up an original thought or response. The only thing I could think of right now is that maybe you could attempt to (subtly) broaden her own horizons a bit and open her up to thinking independently and talking about things that interest her. Talk as little as possible about yourself and dig around to see what’s going on in her life, try and stimulate her own brain instead of just dominating whatever interactions you have with her. Encourage her to develop her own curiosity about things and help her to build a more, shall we say, socially imaginative personality. I hope this helps lol, could be useless advice
