Asking questions is how most people show interest. That doesn’t mean it’s disingenuous. Conversations are not events where people take turns talking at each other, they’re back-and-forths.
On the flip side, have you thought about how disingenuous it can seem when someone says nothing while you talk, and then immediately afterward starts talking about themselves and their life at length? Most people don’t just automatically update everyone around them on everything in their lives, that’s why people ask questions and show interest.
Gender Bender!
EDIT: It’s Bend Her… I like my pun more :P
Gotta get that Femmzoil
