Lavender managed to rid the frown from her face and replaced it with a little smile, "Why wouldn't it be fine? You just surprised me. I didn't know you two were... interested in each other. Like that."
This was the most difficult part, so Lavender tried to rid any images of Parvati and Seamus together from her head. Since Neville didn't answer her, she took enough from the top that it would be tidy, but would look better than usual if he styled it at all. "Almost done..." She said, cutting his hair carefully. When she finished, Lavender pointed her wand at Neville's hair and dried it, then tousled it with her fingers. Another flick got rid of the hair on his shoulders and the ground.
"Hang on, I've got some wax," Lavender reached behind her and produced a small tub, "You can keep this. Just do like this." She put a small amount on the palm of her hand, rubbed her hands together and carefully styled Neville's hair. "Don't you look handsome! Isn't he handsome, Parvati?"
