Mask.
"They don't seem to understand it at all. Every morning, she walks in, dreary-eyed, only to find a mess that could have easily been taken care of the night before. Yet nothing is ever done as she likes unless she does it herself. If you want something done, you have to do it yourself is what she lives by. Still, she can't believe that she has to deal with such impudent fools that have many years on her, who are much slower than she is and don't seem to have much common sense. She tries hard to smile and laugh it off, but she lost her main pillar of support. She loved her, not romantically, but more admirably. She was a role model to her. Though they didn't see eye to eye for many things, she could always rely on her to lend an ear and patient mind to listen to whatever she had on her mind. But, now she's at a distance. She wakes up every morning, in her cold, dark apartment, knowing that the day's going to suck and she'll have to keep her mask tight to her face. It's a difficult task, but she tries hard so no one has to see her negativity, so that everyone else may have a pleasant day. That mask has worked for so long before; she knows it's due date has yet to come."
