I think hate is a strong term although Im sure that might be true as well in some circumstances.
I have 2 sisters and they are worlds apart. One has serious issues with herself and her family and is the dominant ruler in her family , the other and the oldest, a bit bossy and interfering in the other sibling's lives. For example, she once tried to stop me from going on a trip abroad with my girls. The reason: something could happen to me. So too much of a mother figure and controlling. She also loves to brag about her very successful children. Its not something one wants to hear each time she calls.
So not hate, but wishing they were a bit different.
The only true wisdom is in knowing you know nothing.
