Yes, not Complaints, but Complains.
Can you go a whole day without complaining?
Are you complaining day in and day out about the same thing?
Are you willing to do anything about it or just keep complaining about it?
If you want to keep complaining about it, no need to share with everyone, you made the choice, find a room, vent away.
But if you want to do something about it, start tracking what it is and what you can do to erase it from your daily view.
Who wants to waste their time complaining about the same thing over and over again?
