Those Who Miss You

I’ve been working odd hours for the last few weeks on a project that required little contact with other people.  My normal arrival time was somewhere around 4 PM and 2 AM and most of my coworkers haven’t said anything.  Today, on my way out around 11 AM I ran into the person who runs our cafeteria:

Her: Where have you been?  We’ve missed you.
Me: I’ve been working odd hours and my meal needs haven’t really synced with when the cafeteria was open.
Her: That doesn’t mean you can’t stop in and say hi.

The only person who noticed my absence from the normal work day was the head chef.  I’m not quite sure what this means.
