Not really. I was taught/extrapolated at an extremely early age that showing emotion equated to weakness (just how I grew up -- this is not a generalization or by any means always true). It ties back to:

I'm a big fan of relatively hands-off parenting (from experience as a son, not father)

...but I don't really feel like going into that right now.

So if I ever did have a short fuse, which I'm sure I did as a child, I learned to ruthlessly internalize it. I happen to be staring at something hanging on my wall that illustrates this in an entertaining way; this past Christmas my coworkers and I did a "Secret Santa"^ gift exchange and the gift I received was a Grinch shirt with "the many faces of the Grinch" -- happy, sad, angry, etc. on it. My Secret Santa had printed a picture of my expressionless face out and pasted it over the Grinch's. So now the face, mine, is the same for every emotive descriptor. It was a great gift.

^we had to call it "Elusive Elf" for political correctness I swear to god I'm not making that up

EDIT: chess pie.
