how i got into a fight with a gen x

well no one asked me to tell this story BUT i am going to tell it anyway because i am a chuddd. ANYWAY i was buying some shit for school and i spot a trapper keeper  like it was sent from the heavenly gods from above i make my way over there  just to get pushed by a lady on maybe her 60's or 50's and i was like ' why did you push me ma'am' and she was like ' i didn't push you you were on the way ' i got mad but i didn't say anything because if i said something it will come out rude so i grab the trapper keeper and then she snatches it from my hands and i was like ' ma'am i got it first' and she started to deny everything  then she said' DO YOU EVEN KNOW WHATS A TRAPPER KEPPER?' and i was like ' well fuck yes  i do you're holding it right now and i need it for school' she got SOOOO MAD and i asked if she was shopping for her kids or idk then she said she didn't have kids and then i was like 'why the fuck do you want it so bad, you know what you can shove it where the sun don't shine' i did curse at her because i was so mad and she already pushed me which i hate when ppl do that. LONG STORY SHORT i had to get the trapper keeper in another store because her greedy ass bought them all.
