Calling String Bets: Rude?

[jafeather]

It all comes down to how casual your home game is.

If it's more of a social gathering that happens to involve poker, then don't get nit-picky.

If it's more of a game, and the socialness is the by-product (i.e. if the game moving slow because of people chatting is a piss-off instead of the norm, etc.) then encouraging correct play is the right move. You're saying "we like to have fun, but this IS a serious game."
