And I would not have expected you to write about something that needs to be changed (in that tone) and doing it yourself immediately afterwards. Why then write about it before fixing it, or in fact at all. Didn't make sense to me.
Also, my thank you could be seen as equally directed towards the stranger that got your hint.
