I don't know what mold I fit in here. I am a "highly sensitive person" (HSP) according to the book, but I don't cry or get emotional over everything, either. Like I don't think I cried when I saw The Notebook? I didn't particularly like it, either.
I have cried at work a couple of times. Ugh. I cried one time a guy yelled at me in the drive-thru and refused to pay before getting the food (only one window was open at that hour so he was supposed to pay and get food at same window). Then the jerk drove off without paying. I don't think he was armed or anything, but I don't like conflict like that.
In the examples of a nasty note or someone yelling at me in traffic, I guess it would depend on if it was really jarring or something easily to dismiss as to how worked up I got about it. And how emotional I was when it happened. I can get tense in driving situations.
My grandma couldn't physically cry I think in her older age. She said something one time like, "I would cry right now if I could" when something happened, but I think she meant that literally she could not cry. Maybe has to do with tear ducts.
Dh showed me some dog commercial... probably Hachi. It was sad, but I didn't cry. Maybe because I don't own a dog. When I was pregnant with ds I tried to watch Finding Nemo and I started crying within the first few minutes so had to turn it off.
