The reindeer one is rather off, but then the silly ones often are. I don't take those particularly seriously. ;)

Parts of the phlegmatic temperment fit very well -- especially the negative bits at the end! I am rather lazy, easily stuck in ruts, and too dependant on the approval and company of others. As for being cool, calm, and collected, that depends. Where other people's problems are concerned, I think that's mostly true, but when things go badly in my own life I frazzle easily. More answer than you bargained for, I'm sure...
