One day, people are going to learn that posting something publicly on Facebook means that people can see it.

27-year-old Kaitlyn Walls is a single mom from Dallas, Texas. Earlier this month, she got a job working at a daycare.

The morning before she started, she made this post on Facebook, "I start my new job today, but I absolutely hate working at daycare." Her new bosses saw it and fired her before she could even start.

Then a mob of angry mothers on Facebook found out what she'd written and started attacking her, so she tried to clarify, "Lol, it's all good, I just really hate being around a lot of kids."

That's not much of an improvement.

Kaitlyn realizes now that she shouldn't have vented about her job before she started and if she does have issues in the future, she's not going to put them on Facebook. "I'm not going to post anything, no matter how I feel."
