He was answering her question before.
When she accidentally barged in while driving, she ran into the little robot and asked it, "Are you alright?"
Christy chuckled. He looked so soft that she wanted to touch him.
While thinking, she really reached out and touched Trevor's head.
Trevor froze.
Christy stroked his hair like patting a cat and said, "Very soft."
Trevor's ears turned red.
Because his hood had been taken off, Christy easily discovered his red ears. She laughed in disbelief, "Your ears are so red. Are you ... shy?"
Trevor didn't know what to say.
He put on his hood again and lowered his head.
Christy stopped joking with him and pointed at the computer, "Back to your work. I'll rest for a while."
