My mom is a Taurus and I'm a Cancer, yet we never seem to get along. At all. Why is that?

Agreed people are people , okay if you get a ton of cancers or taurus or aries or leos or whatever sign , you think they are going to be the same ? NOPE. I know how they say this sign is compatible with this sign and they generalize everyone in groups , but its not true and people shouldnt take it seriously or base their whole life on that .
