Sierra drew in a deep breath. Well, at least they were silenced now, which made her feel a little more comfortable. She opened her mouth to speak, but then she paused again and cleared her throat. "So anyway, I've been thinking...," she started again. "Excuse me, Professor. I don't do this sort of thing often." Going out of her way in an attempt to make someone else smile wasn't exactly her kind of thing. This was completely new territory for her altogether.

She drew in another deep breath. Okay, Greingoth. Spit it out and get it over with. "This was your first year teaching here at Hogwarts, right?" Or, at least, the first year Sierra knew of. "I just wanted to welcome you to the school, since I never really did that before." She'd been sort of quiet in class, which was her comfort zone. "I know it's the end of the year now, but it's never too late to correct a mistake, right?" She gave the professor an awkward grin. So far, this was going a little better than she expected it to.

"Anyway, erm..., thanks for a good year, and..." She trailed off. Merlin. She should have practiced this in front of a mirror or something. "...I also wanted to ask if you needed any help wrapping things up for the year. I'm done with my homework, so I just thought I'd ask if you'd like some last minute help cleaning up the greenhouses or the gardens before we leave for the summer."
