Alright. Let me just say this first; telling someone they're too skinny is just as rude as telling someone they're too fat.
Second of all, it's none of your business what people weigh or anything of the sorts. People CAN be insecure about being skinny. Sure, it'd be nice to be skinny but what if they want to gain weight? Skinny shaming is much too common nowadays, as is fat shaming(?).
So ye. Sorry just had to say that.
