Well it's not like I'm not like that. That's one of my finer qualities that my Gemenii ex loved about me: that from a simple conversation about "what to have for lunch" we can discuss things as far as...well...anything. With me, in real life at least, a conversation that lasts for an hour would have convered at least 30 subjects. Trust me.
That said...the difference between that behavior and that of Geminii is that I know where I do need to have focus (i.e., not whoring around when I claim to be in a happy relationship, listening intently to a big whine-fest when needed...etc...and my god, Geminii are the biggest whiners ever. Ever.), whereas Geminii can't focus at all, or only by giving itself some incredible and permanent head injury. It all means they're prone to cheating, lying, misinforming, and concealing the truth...just so they can remain to be "light and breezy" and follow their ever-changing whims. And again, it can be a lot of fun...but it gets old quick when you wake up next to it.
