(Clapping hands in a really soft supportive way)
Ummm... I honestly appreciate that you care enough about me to critique everything that goes into my mouth while at the office, REALLY, I do. It is sweet.
However, at the moment there is A LOT going on in my life that you don't/can't truly understand... and thus I need some serious chocolate every now and then. (By "serious", please read 4 mini candy bars - not like a whole bag or anything.)
I think it is great that you want to encourage me to reach my goals, and that you are an aerobics instructor - but without sounding like a hormonal mess... BACK OFF! Go back to your office and do some desk push ups or something constructive... because it honestly isn't helping me much at all to have you pop in and give me the look of disdain.
It also makes me wonder how I can get from my cubicle to the candy dish and back without passing by your window.
So - lets be friends, and just pat me on the back and tell me it'll be alright... and leave the judgy comments about my choice in snacks to yourself.
