Peaceful co-existence

Hi steemians, talking about peaceful co-existence, i noticed many people out there in the world find it difficult to live with others without quarreling or having one issue or the other on the daily basis. You know i had this neighbor once and each time we were all jesting or making fun out of our selves she always turned the table around, getting annoyed suddenly and causing everyone to disperse quietly as if we weren't having a conversation seconds ago.
I also had this friend that comes looking so happy and tries to hug you and when you hug her she's like "abi this one is high ni", and she pushes you away and you wish it never all happened...
Do place comments of your experiences if you had something of this nature, i mean people can get angry so easily i dont understand any longer...
whats your take, whats your experience, lets talk...
m waiting....
