Should Reflex On Her Actions

(I’m the oldest of five children. The sister closest in age to me and I do not get along very well, and I generally find her irritating. My youngest sister is a toddler, and is pestering me to play with her by pushing and pulling on my legs while I lay on the couch. I’ve just got done babysitting her all day and my patience is running thin.)

Me: “All done. No more.”

Baby Sister: *ignores me*

Me: “I said no more.”

Baby Sister: *ignores me*

Me: “Ugh, [Older Sister], knock it off!”

Mother: “Did you just call her [Older Sister]?”

Me: “Well, usually [Older Sister] is the one who’s annoying me! It was a reflex!”
