I'm sure there used to be a thread like this but the only one I could find was from years ago...
Anyway! Here's mine:
So our daycare just had a cake stall so I baked a heap of biscuits the other night and wouldn't let DH/DS have any because "these are for the fundraiser!!". But when I got there, the other parents had done such a good job of donating so many home-made treats, I figured my biscuits weren't needed. So took them home and ate the entire box before anyone noticed
(I still made a cash donation and spent an hour on the stall, so figured that made up for it at least!)
So what guilty but harmless secrets does everyone else have so I don't feel alone?
