Awkwardness

So I moved from a small town to (at the time five years ago) me "the big city." We'll now I know it's not that big anyways... Everyone I know from back home loves to come to eat at the restaurant I work at. Does anyone else think it's awkward to serve people that they haven't seen in forever? Or not even serve does anyone else find it awkward to see people at the store or walking around the fair or anywhere for that matter? Some of these people I don't even talk to I just notice on my way back into the kitchen. I'll think about stopping by to say hi but it's been five years... Hince my awkwardness... Idk I'm weird...
