Hi Mark,
when I was reading your post, I was thinking "oh, didn't I just wrote this post?!". Every single word..
My sarcasm was never too hard or common, but after a few people, that didn't know me well, told me, that I am a bad person (based on a few of my sarcastic comments), I thought over this "sense of humor" and now I am trying to use it only when I am 100% sure it won't hurt anyone and/or the people will understand
