Me, Myself, and I

Me, Myself, and I
More like 3 or personalities in one body
Do you ever wonder why sometimes we;

1. Love, then hate, and other times we don't even feel anything?
2. We are happy, then become sad, and other times we are just like some robots without emotions? 
3. Sometimes, we may want something, other times we reject it, then sometimes we don't even know what we want?

It almost feels like there are 3 case scenario to everything, just like we are expected to eat breakfast, lunch and dinner or greet people good morning in the morning, good afternoon in the afternoon and good night in the night. 

Me, Myself, and I. Could the above have been a conversation between 3 people in my head?
Do you have conversations with your self and somehow think that you are conversing with 3 people?

This was probably a 3 people thought, so read and enjoy.
