Call me retarded but just now I noticed that the hints that you get through events aren't the same as the pool of skills in the "Skill" tab.

So basically... The skills from the "Skill" tab are the exclamation marks that you see in Training (the events that are really short, just like 3-4 dialogue boxes and then poof, you get the hint), meanwhile the skills that you get from the "Career Events" tab are the longer events that you need to farm Friendship Points.
Is that right?
