01 Everyone agreed to bring one thing each, and you ended up prepping three extra portions
If a shared arrangement keeps having you fill in the gaps, look first at what you actually agreed to versus what you quietly took on because nobody else spoke up. This page isn't telling you to stop cooperating — it's putting the division of labor back into a range that can actually be confirmed.
02 Ask before you cover someone else's part
Sometimes the other person is still working on it and just hasn't updated you; sometimes they genuinely need help. Asking directly is clearer than assuming in advance it won't get done. If someone does it differently from you but it still meets the shared standard, you can let the result stand as theirs — you don't have to quietly redo all of it.
03 Turn the next step into confirming the division of labor
You could say: "I'll take care of this part — what do you still need on your end? If we're running out of time, let's talk about narrowing the scope together." Don't promise to take everything on yourself first and then hope someone notices how tired you are. This random page isn't judging who contributed more — it's just a reminder to keep helping as something you choose, so everyone knows which half they signed up for.
