In the first one, the group would just not get to agree at something, they'd spend hours talking about an approach.

First times, I was like "Hey, why don't we do this?", they began to argue and half an hour later, they agreed to whatever I said in the first place (they didn't acknowledge what I said and they tell me they came with the solution and that I didn't say anything)

Fucking shit, if only they listened in the first time.
