Hmm...the professor was rather cheerful today, now wasn't he? Well, she supposed he had reason to be. If her house had just won a rather competitive Quidditch match, she might be going around smiling a lot, too.

Sierra, though, had always been sort of leery of overly-cheerful people. They usually had something up their sleeves, or they either wanted something from someone else. That line of thinking was just based on her personal experiences, though, so one couldn't exactly tell whether Vindictus was sincere or not.

Just in case, she gave the man a small, polite smile as she reached for a broom and then found a seat around the work table.
