I'm not sure apathy is the word

Years ago, Gloria Estafan advised me that the rhythm was going to get me -- I'm only just now starting to lower my guard. 

I saw Mom and Dad on Father’s Day a couple weeks ago. We were talking about how extremely hot weather can lead to people dying where they live, like in Chicago in the summer of 1995. My dad said he didn’t understand why people didn’t know enough to get out of the heat. Later that day he said he didn’t understand why some people kill themselves in response to online bullying. Every Father’s Day at some point I think of the same question: What word means the opposite of empathy?

Every time I see that thrift shop advertising three socks for a dollar I have a mental grimace.
