I feel the exact same and I'm going to agree with every single review above, but writing things like this sometimes doesn't help the situation if it's genuine, yo'know? It just makes them feel shit. I don't know about the other ones, but I know that one of the notes was genuine because it was my best friend and.. eh, well, I dunno.
Although, a few comments from a stranger can help enough to push them away from the edge. The closer you are to someone, the less a compliment means, in my opinion. It feels like that to me. :)
But I totally agree with you. 100%.
