Not everyone likes having faults pointed out, though.
Good point Richardsk. However, I think there also is the element of how you approach the person. For instance, I would never offer up advice to someone I have never seen at the pool or spoken to. But yesterday when I was swimming, a man who overall has a decent technique, kept slapping his right recovery arm into the water rather than spearing it. I asked if I could point out something too him and he agreed. After I explained what I noticed he graciously accepted the advice. I also let him know the reason why I noticed is that the same thing had been pointed out too me.
