There'a 11 years old kid in my neighbourhood, he often keeps checking my pencils. I tell him not to touch especially the thin graphite leads as they are fragile but still he ignores it and broke a few and again don't stop touching them. I don't know how to react it. The more I tell him, the more he ignores.
Note that I don't care if it breaks or not, won't cost me much. It's just I don't know how should I react to it.
