Re: The cranky thread
The problem is that for any of your daily (or even weekly) acquaintances, such changes are too subtle for them to notice til you mention it, at which point they do a mental rewind and realize that yes, you DO look different. Someone who knows you as well, but hasn't seen you in a month or more, is a lot more likely to notice, because you have "over night" significantly altered the "pattern" you fit into in their head.
You're your own best cheering section for stuff like this. Sadly, most people suck at that, to one extreme or the other.
