Cupcakes have been my enemy here lately, but I've had the power to say no. Since it's the end of the semester, everyone keeps having shindigs and making cupcakes for them and this conversation happens every time:
Person: *shoves cupcakes in my face* LOOK! I MADE CUPCAKES! EAT ONE!
Me: No, I'm at my calorie limit for today, I can't have one right now.
Person: But I made them!

Me: I know, and they look delicious, but I really don't need to eat that.
Person: You can have one every now and then!
Eventually they leave me alone, but it is rather frustrating. I'd love to have a cupcake, but I know that if I were to say yes to every single cupcake offered to me, I would not be where I am today. I do feel bad having to blatantly tell them no like that, but sometiems people don't wanna listen.
