RAG IN THE SINK

My brother was doing that thing he did. That thing with the rag in the sink. I couldn't understand why does he always do that. It seems like he can't get the idea that what he is doing is not the proper way of doing it. For how many times that I talk him of it still nothing seems to register with him.

What's wrong with following instructions from our mother on what not to do and what to do with that rag. Well I guess because he doesn't like working on the sink so he made it sure to send the message. Having such kind of act is annoying and is not helping at all. For so many times already he had been doing such thing and its not helping.
