do any of you get extremely paranoid or angry when someone tries to 'help' you with your art? for instance i'm working on one drawing right now with those g pilot pens everyone has...well when i have free time in class i work on it and out of nowhere a 'friend' (quotations marks because...well i don't really like her all that much) decides it would be a good idea to get out the same type of pen and 'help me' finish my artwork. (i didn't ask for help, either) but as soon as she started coloring in stuff i was seriously having a huge panic attack. i think my heart sped up and i was seriously freaking out because, well, it's my art. the whole time i was like 'she's gonna mess up, she's gonna screw up my art, she's gonna mess up, omg, omg". she doesn't know much about art so that also scared the balls out of me. she ended up ruining a part of my drawing that i had to go over with black to fix. :[

so i was just wondering in general how often does this happen to you guys or if this happens at all to you, and what i should do/say to this person to get her to STOP 'HELPING' me with my art? she's a sensitive kind of girl so i'm afraid of saying anything that could hurt her feelings but she won't stop trying to help me with my work :[
