children enjoying kolams

When we make kolams/ rangolis kids enjoy and they also try to imitate us by putting some of their imagination and say Wow! But when we are not around they put their hand on that and enjoy playing on that. "potta kolam azhikka kuzhandhai vendum"( we need a child to erase the kolam drawn at home) is a old saying.Here you can see how these two, 3+ are enjoying.We get upset at the same time cannot help admiring their enthu.What u say?
