Yes, that happens, and I'm sure has happened with others toward me. The things is, we do all we can. Speak, act, think, pray...but at the end of the day, the only ones who can change us (apart from God) is ourselves. We always strive, however, to help others in every way we can. Wesley said:
“Do all the good you can. By all the means you can. In all the ways you can. In all the
places you can. At all the times you can. To all the people you can. As long as ever you can.”
