“Hey, Natalie! Nice sweatshirt!”
I was passing through the hallways of school last year, being messenger boy for the teachers, when this girl walked up to me. I had no clue who she was, but I thought she was a year younger than me. That’s why I thought it was weird that she said my name. But the “nice sweatshirt” bit was what really got me.
I wasn’t even wearing my sweatshirt.
So. There was a substitute teacher in my literacy class, so my class was split. half of us did actual work, and the other half watched a documentary. Ben, Evan, Isabelle and myself were put together in the class watching the super boring documentary. We got bored, so, when Ben left the classroom for a bit and left his jacket behind, I don’t remember why, but, I put on his sweatshirt and traded it for mine. This turned into everyone swapping sweatshirts for the next hour until school was out. At one point I was called to the office to deliver a message to a different classroom. I walked out of the office with the information, and turned around at the sound of my name.
“Hey, Natalie! Nice sweatshirt!” I smiled and thanked her like the nice human being I want people to think I am. Once she started down the stairs I looked down at my sweatshirt. Black and orange? Nike? But my sweatshirt’s gray and purple! Then I remembered our little game of “try not to get caught swapping sweatshirts and giggling”. I wasn’t wearing my sweatshirt. Someone else had it. I was wearing Evan’s.
It’s also kind of sad because that was one of the only compliments I’ve gotten from a stranger all year. Complimented on something that wasn’t even mine… Welcome to my life, everybody!
