I get really tetchy and I snap at everyone. It really seems as if people ask me more pointless questions when I'm tired, so I get angry at them for 1) not noticing I'm tired and 2) persisting with their stupid questions. I also get really dopey and forget things I've done moments earlier...
What's the best remedy for a sore throat?
That girls are raped, that two boys knife a third,
Were axioms to him, who'd never heard
Of any world where promises were kept,
Or one could weep because another wept.
