Some phone calls I get from date potentials basically result in her just chatting my ear out.

I can overtake and generally chime in and steer the convo, but I think the chattiness is because of nervousness or excitement. This in itself shouldn't be a bad thing and I think the more the person talks, the better she feels or the better the convo is. But I'm looking for someone who can at least balance a convo.

The chit chattiness can be annoying, especially when she just doesn't know when to stop or literally chew my ear out. Am I being too serious or am I losing the convo? Why are some women generally just over chatty? I notice this too with leads I get who are a little below average because of course an average chic nowadays can be seen or feels to be 8/10 but this is for another topic.. What can we say when she just gets overly chatty?
