I never thought that I would last a month so I, too, celebrated like mad when I hit 28 days. Perhaps Mrs. Sarge was equally nervous about quitting.  Don't be a grinch, Sarge, give her a reward for BOTH 28 days and the 15th of the month. 

She has done awesome, we won't split hairs on 2 days of a great job, well done Mrs sausage, now make sure the sarge treats you to something nice :)
