Model Question About Feeling Rude with Food


Hi there! I’m a bit confused on my model, can you help me with this?I feel rude when I turn down a plate of cupcakes and only ask for one. I don’t want to be like that. I have had people in my life like that and think, why can’t they just take the plate and not eat them?

C: plate of cupcakes and I took one.
T: I shouldn’t have done that
F: rude
A: dwell on doing that, question myself, judge myself,
R: I did do that.

This is where I’m getting thrown off. Is that my R? If i don’t want to be someone who only takes one cupcake or can’t be around tempting food, should i just change my thoughts about it? Thank you!
