Amen, RE the going-to-bed-angry. Little things that, if allowed to marinate over the course of the day, would no doubt otherwise work themselves out of your system (even if it's just by distractions caused by other things, or you trying to convince yourself that the person or community responsible just plain sucks), instead get blown out of all proportion in your head for the sake of having gone to bed without working through 'em. It's NOT fun.

...what? I have no experience of this...

Also, the apostrophe thing made me giggle. For years and years I just went -'s on everything, singular or plural. Learning the difference between singular and plural rules when it comes to -'s versus -s's was... embarrassing, to say the least.
