Smells like pre-teen spirit

I saw that my local council added what looks like a painted edge over the encroaching grass that has begun growing onto the loose gravel footpaths. I presume they had used this to poison the grass into complying with their urban landscaping aesthetics and order.

It’s uncanny and a little unnerving how identical the poison’s aroma was with the smell of permanent marker pen that my primary school classmates and I used to sneakily love to sniff when the teacher wasn’t watching.
