Pencil Lead Art

Sometimes, you really need to be alert and also, be aware of your surroundings. This was because with the two girls around, I really had to be stingy when it comes to praising them. Oh, they're good with their imaginations and all, to achieve the end result. 

But its the middle process which really gets them into trouble.

Take this pencil lead art for instance. Its nice and very creative of the girl/s.
The the next question that comes to your mind:
How can they finish so much pencil lead in such a short time since their daily homework did not involve writing lines and lines of text.

So, now, I have to be very suspicious when they ask for more pencil leads...
