This has been bugging me since my show

I went to the Brisbane show on 21/11. Literally best time of my life, i had tickets for their concert in 2018 but i became way too sick and couldn't go. I fully dressed up for the concert, had the clancy tape, blurryface neck and hand paint. I was in the upper circles because of chronic illnesses that don't allow me in the pit and i sat next to a group of women probably in their late 30's/40's. Just after the opening act, the lady next to me says "i'm sorry, i have to ask but is this tattooed?" Referring to the paint on my hands. I said "nope, just paint". She says "is it a twenty one pilots thing? Because i've seen like four people have it" and obviously i said yes and explained a small synopsis. I was a lil confused because obviously tyler has it and if you've seen any twenty one pilots content you would know. Then she said "that's so strange because i've seen them 4 times and ive never seen it before". Felt like i was fully gaslighted and genuinely so confused?? During the concert she didn't really sing along and was like really surprised at a lot of things. But when 'stressed out' and 'heathens' come on she's like "YES THIS SONG!!!". I'm genuinely just confused and definitely think she lied just for no reason? I wasn't gonna shame her for not knowing what it was... has had me heated since lol.

SHE ALSO LEFT BEFORE TREES SO...
