Ok, I will make sure to not forget this comment

I just hope you learned your lesson and that you ask first before helping people with their drawings.

Well im sorry for how you feel for erasing your sketch,
I was trying to be chaotic,
But I took it to far-

Well I was to lazy to draw the letter and I was focused on drawing something,
I was just playing,
Well you could've said to stop so I wouldn't be chaotic.

You could’ve just asked if they wanted the help instead of drawing on their drawing and not saying anything.
Plus if the person didn’t like it you couldve stopped and let them do their thing.
