It's kinda funny. The whole "I listened to stories at the feet of my elders" thing doesn't bother me in the slightest. It's plausible, and I applaud players who want to add more backstory into their characters during play. I think that sort of thing is great.
What does bug me though is when players try to, what I see as, game the system. Yes, my character has no training whatsoever in persuasion and a below average Cha, but, because me the player can do good talky talky, I don't need to spend any resources there because I know that most of the time anyway, I can convince my DM that I don't need to make a check.
Play the character you brought to the table or bring a different character.
How about instead the player plays his or her character how he or she sees fit - provided it's fun for everyone and helps contribute to an exciting, memorable story - and the DM describes the environment and narrates the outcome of the character's actions without telling the player how he or she ought to play that character?
How about the DM gives Inspiration for "playing the character you brought to the table" instead of seeing a player playing a game that puts no limits on action declarations as "gaming the system?"
