Coworkers: To Date or Not to Date?

Coworkers can be rude sometimes. This morning I walk in and the receptionist, the girl I was interested in, looks down at her phone the whole time and does not greet me. The next coworkers walk in and she immediately greets them. The coworkers did not address me either when someone needed to talk to me, so I had to find out myself who needed to talk to me during my shift. They have their cliques and small-talk banter, but they never speak to me.

I won't force my company on anyone who doesn't welcome it.

I'm starting to wonder if PMO is karmic. Yesterday I did PMO and 20 or 30 minutes after my other job's shift was suppose to start, I find out a few phone calls later that it got cancelled. If it is karmic, maybe this would explain the cold detachment from my coworkers.
