Why are some people so insensitive about the death of a loved one?

Yes death is part of life but thay doesn't mean you have to be a jerk about it. I lost my grandfather two years ago and a girl that used to be my friend was so insensitive. She was nice but then like a week later she wanted me to come over to her house to get my mind off if things. She got so rude, insulted me and manipulated me and didn't care how I felt. She even shoves and scolded at me to stop crying and people die and get the hell over it. She says she hates it when people make a big deal about someone dying and people crying so hard about it.
