Why are women so mean and cruel? I hate my job....I didn't realize I was such a hard person to work with until my co worker moved all her shit out of the office while I was home sick yesterday. We were pretty close, but I guess that's gone now. My trust with her is gone. It doesn't help that I have to work with her every single day. If I could I would have left and never come back. To add to this...it's my birthday today and now it's all ruined...
