how do u deal with defending urself when u have a delayed thought process/response?

SOME DUMB AH BITCH WOULDNT MOVE OUT THE WAY AND PROB DIDNT HEAR ME WHEN I SAID “EXCUSE ME” SO I JUST WALKED THROUGH AND AS I WALK AWAY I HEAR HER GO “an excuse me would be nice” AND I WANTED TO SPEAK UP AND DEFEND MYSELF RIGHT IN THAT MOMENT BUT MY BRAIN WAS LAGGING AND I COULDNT THINK OF ANYTHING TO SAY SO I WAS ACTING LIKE I DIDNT HEAR ANYTHING LOL

whoever was with her was also like “she did say excuse me u rat” 🤣 i know that’s right!! i won’t stop thinking about this until i forget about it, i hate how i can’t think of the right words to say in heated moments where i get triggered ugh
