Coffee ring. On the coffee table. Next to the coffee table book. Hate that. Untidy. Sign of a weak mind. Use a coaster. Or at least clean up after yourself. Who does that? You sloshed the cup, had to see that, set the cup down anyway, on the table, next to an obviously expensive hardcover book, then picked up the cup, seeing the mess, and walked away, like it didn’t even matter. Unkempt, lazy, disrespectful, irresponsible, and a few other choice descriptors I’m afraid you wouldn’t appreciate.
