Is it normal to not be an emotional woman?

I have never been overly excited about anything in my life. I don't seem to have many strong feelings, except for anger, and annoyance. I don't let sappy movies get to me, or sad stories, or anything. I really don't know how to react when ppl are crying, or when they tell me about their family being terminally ill because I truly feel nothing for the situation. I work with the public and I can fake being a helpful caring person, but that's exactly what it is FAKE. I see the general public as sheep, who more often than not are just out to sastisfy their disqusting selfish urges. For example - the crackheads, the hookers, the gluttens, and the snooty prissy bitches, also, the guys walking around acting like they are something but nobody (especially me) gives a shit about their lives, problems, etc. I truly could care less if these ppl were smoked by cars one after another. I would be more entertaning to me rather than anything else. Is this normal or am I a horrible person? The only ones I really care for are children and pets as they are innocent.
