Do you talk a lot? Do you remember everything you say? Is it possible that you might have said something that:
a) inspired someone
b) motivated someone
c) bored someone
d) insulted someone
Possibly. Probably. Sure.
Even beyond the point of your remembering what you said. I've said things that I later regretted long after being able to remember what it was that I said. The feeling remains. Someone else retains the message (even if it's not the message that was intended.)
Everything you say is remembered by someone. How do you want to be remembered?
