H: I wonder if there is a program called Impulsive Anonymous, you know?
M: Yeah sure there is. It is called growing up.
H: But what if I have the Peter Pan syndrome?
M: You don't. You just wish you did, for then you would be able to justify all that craziness that I have to curb.
Most dictionaries consider "uninhibited" a synonym of "impulsive". And yet, one is more positive than the other- maybe because the former is what it seems like in the present, and the latter is what it seems like in hindsight.
