Who leaked out the proposal day info??

Dunno why recently dun feel like blogging.. But lots have happened, and its all good.. Today is my last day at work in Temasek Polytechnic.. Collegues here are good to me and took care of me well.. Lucky.. 

Left with 5 more days with the 6th day the actual event.. Somehow or somewhat, my gf already noticed about my proposal thingy yet she keep quiet about it.. Who the hell leaked it out? My ring is hidden at the back of my cupboard and there is no way she will rummage thru my stuffs.. If i know who say out i will sure skin the fella alive.. I never do anything related to the proposal stuff in front of her, its always away from her so she doesn't know.. I will keep on observing till sunday.. If all is well, i carry on with the plan, if not, i call it off and do it my way..
