Someone left a comment on my sister's blog that I think was totally out of line.
You have to read about it. Go here.
Since when do we begin correcting someones blog? I would never, ever tell someone that they misspelled something or used bad grammar in a blog (because I am sure I do it all the time). It is like like judging some one's journal; something that is written with complete sincerity. It is just not right.
Even if you do notice it...you don't mention it.
I notice that most people who leave rude comments usually do it anonymously. Personally, I think that person is a coward!
