An Awkward Lunch

12:30 pm has always been my lunch time at work, assuming I work the day shift. Two other ladies and I all go at the same time, it's our thing. Were all kind of the same in the way we express ourselves verbally with sometime crude innuendo and the like. Lately, after his recent marriage, our store manager has been eating lunch with us. He is my age but he is the least bit crude. He turns tomato red at swear words. I'm never really sure how to talk to him and today I found myself sitting alone with him upstairs, trying to enjoy my ramen noodles. Do I need to hold a conversation? Is silence okay? If I talk what do I say? I mean besides work, what else do we have in common? Uh... This. This is awkward.
