Hey Best, you are absolutely smashing this, woohoo, go you!
I have found that even though I've lost of 10kg now too that only a couple of people have said anything about it as well. Some days it does make me a bit sad, like, is there really not that much difference? But I know there is and maybe part of it is them not wanting to bring it up, maybe they think you wouldn't want to talk about it or that it isn't something they should say. Some people are strange like that and don't want to hurt feelings or offend.
OR maybe they're just jealous
Either way you are doing a fantastic job, no doubt about it! Can't wait til I'm down that much!
