Yup, he has collected three erasers from the tops of pencils. That may be strange enough for a normal 7 year old. But if you've been reading my blog, you might remember that it was only 2 weeks ago when my son stuck this same kind of pencil eraser in his eraser (You can read the post here). The school nurse couldn't get it out. The ER doctor couldn't' get out. The ENT almost couldn't get out.
So why not have a collection of them, right?
