Bubblegum

I was watching a girl in the bus.She was making bubbles from gum in a bus,full of people.I remember that I was thinking : "Is she crazy?What if that thing gets stuck to someone's hair?"But she didn't mind .. or didn't care.Anyway I tried drawing her when I came back and yesterday (while searching for another pic) I found this sketch and thought that i should post it!
