No friend, acquaintance, stranger, or enemy of mine would need to ask me for help if they injure themselves, regardless of what I'm doing.
This less about lack of empathy and more about common decency.
This reminds me of what happened to DH a few years back (gross alert!). He was fishing on a rocky area of a causeway that the state pours concrete on to make the rocks 'safer' for shore fishermen. Well the rocks gave way under my DH and he fell and badly injured his knee. He was crying out in pain and the hanging skin and exposed bone and blood coursing down his leg
could plainly be seen. His stepfather, fishing next to him, NEVER stopped casting, except to say, "You gonna be okay?" Due to the dynamics of the relationship
(DH knows his step-dad is self-absorbed and really doesn't care about anybody but himself), he clambered up the rocks, got in his car and DROVE himself to the ER (thankful it was his left leg or he would've had to beg for help)!
His mother was disgusted with his step-dad (because I made sure she knew about it) but she knew what kind of person he was.
The best part? His stepfather is a doctor...
