i got threatened

so picture me this, it is a nice yet cloudy day, you're in year 10 (14-15 or Freshmen 9th grade for americans) and you just got out of school, you are walking and people start to crowd up soyou walk on the small wall next to the school's gate. Then, out of the blue, a year 8 (7th grader) comes up to you and asks why you wereon the wall. this happened to me on Friday 6th October 2023. this is the convosation: ("-" means who said what)
him- why were you on the wall?
me- because i can
him, pointing to my bag- i like that show
me, looking at my alice in wonderland themed bag- what show?
him, repeating- i like that show 
me- what show?
him- do you have snapchat?
me, lying- no
him- do you have a phone number?
me, still lying- no
him- do you even haveyour phone?
me, still lying- no
him- do have an ipad?
me, being honest- no
him- now i know you're lying
me- i am not
him- do you want me to fvcking punch you, b!tch
me, in shock- EXCUSE ME?!
him-yeah 
i fake laghs and after a second or two, he laughs. Then i ran. when i got to the bottom of that hill, i was having a panic attack. wondering how i was going to get the techer's help without running into that Andrew Tate w4nk off, i saw one of the behaviour teachers coming down the hill. I told him what happened and he alled my mom, i was scared to take out my phone incase that b!tchlet saw me. my mom was told what happened and i told all of my friends i even told my bf too. school is sorting it out so until i get the name of that sad w4nk, i cannot get any infomation out yet, and more than likely a girl in my form group will ask what happened and hopefully she'll know who i am on about
