Long day at work. I get in the elevator on the 21st floor with a co-worker that I barely know. On the 20th floor two techno geeks get in. One of them is talking non-stop in a loud voice. She is spewing jargon that only her and her fellow geek understand. We reach the 1st floor and we all get out. That is when I turned to my co-worker and said in a very loud voice, "WELL, GOOD NIGHT." No pre-thought, it just came out of my mouth. YIKES! We walked in the opposite direction as the techno geeks and I didn't have the guts to turn around and see if they responded. Neither did my co-worker. I apologized to her for acting like a jerk. She said it was actually pretty funny. So am I grump, a wise guy or just a jerk.
