Too Chicken to Be Genuine?

Genuineness. My friend is sick. I don’t want her to be alone while she’s coughing, hacking, sneezing, honking and moaning in agony. I have OCD. I wash my hands more times than the average man thinks about sex during the course of the day. What’s in it for me? ..The flu, possibly. In my head, while witnessing my friend suffer, I can only think if that were me lying there on the couch suffering with nobody around to help me – I would definitely appreciate somebody coming to my rescue with a hot steamy pot of chicken soup and maybe bring me to the doctor’s office if I needed to. Is it a motive? Is it ‘if you scratch my back I’ll scratch yours’ type of deal? I’d like to think that my conscience tugged on my heart and insisted that I help my friend so she could get better. But then I delve deeper: is it because I want others to do the same for me?
Do unto others, as you would have them do unto you.
So it’s basically a law. Does genuineness come from this golden rule? If it does, is it truly considered being “genuine”?
