Is it wrong to refuse to share lecture notes with a lazy student?

A classmate of mine is nice enough but a bit odd. She's always at least 30 minutes late for lecture, and she doesn't come to lab sometimes. In lecture, she does not take notes but instead usually draws the whole class period. Today, she asked to borrow some of my lecture notes. I told her that I noticed that she was always late and that she didn't take notes, and she denied that. Still, I told her that lending her my notes would be inconvenient, then I suggested that she ask someone else. Normally, I'd be happy to share my notes, but in this case, I didn't want to share the results of my efforts in attending this class on time, every day, and paying attention. Was that wrong?
