So I was at my second meeting about a project I just joined as a volunteer. There's two teachers, me (1st semester CS), a guy almost graduating and a guy in the second semester. In the first meeting the teachers explained what the project's about and what we need to do. Me, wanting to show that I'm good hoping I'd get offered a paid position in the future, got to the second meeting with some stuff already done in Rust. Teachers mistook me for the 2nd semester student (which, by the way, thinks everything server-side is done in node.js) and told him it was a very good job "he" had done with the rust program. The fucker didn't say shit and just took all credit for what I did.

Later that day I sent an email to everyone with the repo link to make sure they knew I was the one that wrote the program and a month or two down the road I made some pretty awesome work while the other two just sat on their asses, so I think they know it was me.

Nonetheless, I got pretty pissed about that and kinda regret not saying anything at the meeting. I do think I kinda made the right choice of keeping quiet, trying to show team loyalty (?) or something like that.

Should I have done it differently? Would you say something at the meeting if it was you?
