Actually, that call for an apology was for P-Marlow, for having called you a liar for being mistaken, not for you. Unless you had earlier called someone a liar for having been mistaken, in which case, please consider it a call for you to apologize, as well!

Goodness, well, let me first of all apologize for my untimely apology. Perhaps we should have scorecards. I'd just like to issue a permanent blanket apology for every mis-statement I may make. Since I can't seem to shut up, I expect I'll make plenty more. ;)
