Vera returned the smile at Desiree, giving the older girl a wave as she also shot Professor Feirgrund a thumbs up at the decline for assistance. Painting the walls certainly sounded like a fun activity, and who didn't like a fresh look? But also the 'leaving a mark' thing sounded so... Intimidating. What would she want to remain at Hogwarts?

Crossing her arms over her chest, Ve thought about it - picturing all the memories that had been important to her so far. Expeditions with Atlas were some of her top tier memories which made her think maybe something mechanical in nature.

You know, as long as not inappropriate or derogatory or xyz from the spiels she'd heard numerous times over the years with anything fun.
