What is /bant/'s opinion on this dilemma? Two people are sitting next to each other in the middle of a lecture. Both are relatively average students and are merely aquaintances who don't owe each other any previous favors.

Person A, who pays attention perfectly fine most days, during this particular class, falls asleep for about 3 minutes and then suddenly snaps back to reality, realizing he missed a page worth of notes. After class, he asks Person B for a picture of a page of notes he missed. Person B refuses to show him the notes, stating Person A should face the consequences of not paying attention and it would be against their values to let them take a picture.

In your opinion, is Person B a dick for no good reason or morally just?
