This is quite sweet to read, your meaning really comes out here. Your punctuation is spot on and stanza breaks work well.

I do have a few suggestions though. I'm not sure the repetition of "you" and "your". Especially at the beginning of the stanzas. Definitely at the beginning of the piece but perhaps not every stanza. It feels a bit telling otherwise, rather than showing why they deserved more, the situation surrounding this. I want to know more but you're not giving it up.

I'm also sketchy on the use of "sir" in stanza four. I feel that it's a teacher then but it feels more personal then that and you go on to describe them with peers. A classmate? So why call them Sir?

It's taut and self contained, but I feel that a little more descriptive language would open this "you" up even more to your reader and help us understand this.

Hopefully this was helpful.
