I was trying to think of what a more rational response to this, since I agreed with your points and also used a very similar trick. I then came up with 'The rational thing to do is to say you agree, upvote, and then get back to the other tasks you have, rather than spending an hour worrying about a perfect response, which sounds a lot like the very social anxiety she was trying to avoid.'

I agree with your post. Upvoted.
