[Lalaith]

My barking mad insomniac computer-obsessive brother. We've just had him to stay and foolishly put him up in a room with two computers, including Mr Lalaith's pride and joy, a custom-built machine.
He spent his nights "sorting out" the computers, without asking us first.

As a result of which the custom-built one nearly died and is still very ill indeed, Mr L is going to have to take a day off work to sort it out.
Meanwhile my computer annoyingly cleans out every cookie overnight so I have to re-log into everything each morning, my address bar no longer stores my internet history which means I can't get onto my favourite sites quickly, and worst of all I can't cut and paste stuff from net pages which I need to do for research, because of some insane security system he's installed.
"Don't you find the computer so much easier to work on now," he said delightedly.
NOOOOOO I DON'T YOU MEDDLING PRANNET.
He's gone home now. I swear I heard the poor computers cheer as he left.
