It's natural that people don't get along great about everything. There's going to be conflict, big or small - it depends on how it's handled.
I suppose you're curious, or perhaps this information gathering is how you survive. I'm not upset; in fact I admire it.
Just remember that there are no absolutes when it comes to feelings - if you are honest with yourself, it is possible to feel warmly towards someone you detested yesterday.
Today I am grateful for:
A companion on the train ride back.
A partner who is patient and understanding, who I can really enjoy working with. (Thanks grace! You're awesome)
A friend who sent me a picture of a husky when I was pretty sad.
Today I am grateful to people.
