Ok.

I promise and swear dude:

I'm not going to expect anything from them anymore.
Let's keep the expectations to negative.
Then we'll see how the project goes.. when I stop nagging them to complete their tasks and at least fulfill their duties as group members.
Be more tolerant towards them.
THEY ARE NICE PEOPLE.

也许只要以一颗平常心待他们，我就不会感到那么困扰。

Is it really about tolerance?
Or indifference?
I swear I'll be passive towards them and their work from now on, lest both parties suffer.
Unecessarily.

There can't only always be one source of fuel.
The vehicle we're in has 5 people, and the fuel has ran out.
So goodbye.

Yes, indifference is the key.
