now I dont wanna get more food bc i feel bad

i feel like i messed up like i literally gave my friend my plate so she could take my mashpotatoes and appearntly she slowly dropped down the plate for the dog to clean off before putting it in the sink and i didnt notice so i said “well maybe i was gonna get more chicken nuggets” and then when she offered for me to use her plate i simply said no and she got mad and started feeding her food to the dog
