Sarcasm

Can sarcasm be intended to tell a joke? I'd say yes. I flippantly and jokingly told a lady recently that I wore my name badge for fun and she took the huge huge huge, huge as a house offense to it because it was sarcasm.
The first entry for sarcasm in dictionary.com is:
–noun

1.	harsh or bitter derision or irony.

2.	a sharply ironical taunt; sneering or cutting remark

The lady I was talking to stated the Greek meaning of "tearing of the flesh" and asked for an apology. I hadn't said it in an acidic manner, but lighthearted one if I remember correctly. I thought at first she was joking, but, she was deadly serious, so I of course apologized. I hadn't meant to be intentionally really mean. At the same time after a full minute talking to me and asking me about this and that she goes "oh by the way, do you work here?". She honest to goodness in all that time had not noticed the shinny name badge I was wearing and said as much. I dunno what to think.

Traffic- stopper

I was merrily on my way to work but something happened... I left in enough time to be to work almost 15 minutes early, I got there 21 minutes late. The reason: I sat parked on an on ramp from one highway to another for a full half hour not moving. My car was turned off. The cars in front of me were at a dead standstill as well. I thank my lucky stars I didn't end up stuck on the bridge part of the ramp. It would have been kinda freaky I think. Obviously there was an accident. An accident that shut down traffic. From what I could tell it looked like a van slammed into some trees on the side of the road. Unfortunate.

I kicked myself and called work to let them know I'd be late. Why didn't I take one of the two other ways to get to work? As it turned out I ended up just staying a half hour later than I was scheduled to make up for time lost just sitting there on the highway.
