INFJ and ENFP
INFJ sees the pattern in people and will not treat it as a game. ENFP brings possibilities, said out loud, with feeling, and then needs a quiet day that is not a rejection. Together you can make a group feel like a group quickly. You can also exhaust each other, because one of you is still holding the meaning while the other has already started the next idea.

INFJ needs a why, and gives a lot, and needs the same specificity back. ENFP's enthusiasm is real, and so is the quiet day after it. If you are ENFP, do not make INFJ guess which offers were the weather and which ones you meant. If you are INFJ, do not file the quiet day as evidence that the feeling was fake.
ENFP likes a brief that can still change shape, and should hand the checklist to a finisher. INFJ is not that finisher unless the why is still intact. Keep one fixed point in the week, a conversation that is about the person and not the next plan, and this pair stops feeling like a chase.
