I quit my job yesterday.
The plan (since May or so) was for me to stay home with the peanut but I pretended like I totally planned on going back to the frat house (aka my former office). The last thing I wanted was to get fired while waiting for my maternity leave to begin. Yesterday I called the HR rep, got her voicemail and ended up emailing her my "resignation". Ah well, whatever works.
I am now officially a stay at home mom.
