irritated. my mom teaches violin out of her house, which i don't normally have an issue with because I grew up with this....what does irritate me is that students know to stay in the waiting area, she has a particular family and the little sisters always wander into the living room after being told not to. I just caught the girl doing it again. we have certain rules in place because this is also a private residence....and in the past, students have broken personal items belonging to my mom or, this is the best example, have fallen down our basement stairs because they weren't careful -.-
