I have a hair trigger temper just like my mother did......
perhaps it's because we both were/are cancers?
Cancerians are loyal and kind, but you'll probably find that they're a bit shy and like to hide in their shells as well. With that said, you should know that while they might be reserved at times, you should never take advantage of them. Sure they're patient to a point, but you don't want to see what happens when they lose their cool.
