Input: So this happened a few weeks ago, and for it's been weighing on me since, so I thought I'd see what you guys had to say;

I've recently started at law school this year straight from high school. I chose this specific school because I had experience the previous year by participating in their high school mock trial competition, in which they gave all the participants a free t-shirt, which has the name of the university and "high school mock trial competition 2018". 

Obviously a fair few students who participated in this competition now attend the university, and while there's not been anything said, it's seemingly implied "don't wear the t-shirt to class, you'll look like a tool" kind of thing. (Also worth mentioning; after this incident went down, I found out that the boy had actually worn it to the law faculty orientation and the law student association had called him out on it)

Anyway, a few weeks ago during a mid-lecture break, I saw this boy wearing this high school mock trial competition t-shirt, and as I walked past, said "hi" and started joking around like "Oooh wearing the t-shirt (his name)" and he, goes "all my other shirts are dirty" and I continue smiling and laughing a bit and go "oh sure haha" and continue walking the other way, But as he goes by I hear him say to the girl he's walking with "Well, *she* was judgemental."

I was a little taken aback with this, as I thought it was just a bit of teasing, but to be called judgemental for it got me thinking, AITA?

Worth noting; I had met this boy before and had a few discussions- maybe not firm friends yet, but getting there - I wasn't just teasing a complete stranger. Also he had a reputation amongst us 1st semester law students as showing off a bit, and "flexing" on the rest of us (for lack of a better word) so him wearing the shit fit into his personality
