From the day we are born we learn about our world by our surroundings. We learn from those around us; our family, friends, peers, teachers, etc. We pick up habits, traditions, and even beliefs from others. But one day we hopefully figure out who we want to be, think for ourselves (not necessarily just following the crowd), and that means we may come to see some things differently than what others may see as “normal.”
Because certain things in our surroundings/society are seen as “normal”, people don’t necessarily think about what they say, assuming everyone feels the same as they do.
An example of this is recently a delivery person who was bringing supplies to my place of employment started talking to me about how he was recently out bear hunting. I immediately tensed up. He went on to give me details about how it wasn’t easy but he got him. He explained how he set the traps and had to travel quite far to pursue him. He was so proud of this. All the while he is telling me this I am thinking “do I tell him I do not want to hear this?” and “do I tell him that I am an animal advocate and that I care about all living beings?”
