You both raise good points. However...

...I had no intention of talking to her for so long, maybe just a minute or two. Then when I realized who her mother was, it didn't bother me so much for some reason. I wouldn't say I was 'friends' with her mom, but we encounter each other so much. We work next to each other almost every night and sometimes talk when it gets slow. It's like we're neighbors or something. I'm sure mom's reaction would've been different had she not known me.

But, NO, there is no way I'd talk to a LG for such a long time if her parents weren't already familiar with me.
