expressive social type

We did a personality test of social types recently in Mr Coffee Bean's (because he's funny, looks like Mr Bean but he's brown) class.
Out of the four types : Driver, Expressive, Amiable & Analytical.

I scored highest of Expressive, second in place Amiable.

The Expressive trait as described by Mr Coffee Bean would be someone sitting alone in a MRT train, all of a sudden would just burst out laughing at something. ( I often do that)
Mostly likely out of the 4 traits to be slightly neurotic, out-going and more dramatic.

I'm laughing at myself now~
