Once, that was hell. They're just stupid bunch of people who thinks that they should get more lighter tasks. I've fought lots with them.

What actually they want is you to do all of the work, including theirs. No, they're not jealous, they just don't want to do the work. Whenever I gave them task, they ****ed them. Never done the work right, either it's wrong or different from plan. Just looking at their work, you will see that there is no effort at all. Spoiled brats.... I don't regret argue with them.

It just their mind games. They said like that so you will feel bad and do more work while they sat on your back. Don't let them be.

And if later one of them said truly that you're bad, it's your turn. Tell them to lead the group, I bet they will try to reason with you!
