You could say sorry,"suggested Harry bluntly. "What, and get attacked by another flock of canaries?"muttered Ron."What did you have to imitate her for?""She laughed at my mustache!""So did I, it was the stupidest thing I've ever seen.

Harry suggested to Ron that he should apologize to the woman he has just been teasing, but Ron rejected the idea because the woman had laughed at the mustache he was wearing and Ron knew that if he apologised she might do it again. Ron then asked Harry why he had to imitate the woman which Harry replied with because she had laughed at his mustache. Ron then admitted that he himself also laughed at the mustache, describing it as the stupidest thing he had ever seen.
