Hello, my sim has to do research flirty emotion for his gig

I completed a gig without having my sim research an angry emotion once before so I don’t see it as all that important if you’re worried! I had the same problem with angry emotions, I didn’t want my sim to have enemies so I just didn’t do it. I didn’t know how at first but it doesn’t even take that long to complete it for a job. But I don’t think it hinders you.
