Salty is feeling very sad and hurt, and she doesn't really know why...
At least, she read the book "Mr. Happy" last night. =]
Though it didn't really help much...

She's constraining her emotions and feelings.
Her friends are becoming more like strangers to her. Some whom she used to be familiar with and close to, no more. What happened exactly, and since when did she feel of repelling everything, becoming more pessimistic?

The girl isn't quite looking forward to her job this weekend, as usual. However, she'll still work there for almost all weekends during this holiday, supposedly. If others can do it, why can't she? And she's going to gain more experience to excel, sharpening her service skills.
