Well, Benjamin, this kinda made me lol.
It reminded me of those tv shows where girls say stuff like
"My best friend really likes you..."
when it's really them that's doin the liking.
Okay, on with the suggestion.
Step 1:
Get a camera
Step 2:
Figure out when your brother uses the computer
Step 3:
Check in periodically.
Step 4:
This should'a been in earlier, but make a program that slows the computer down a little.
Step 5:
Burst into the room and take a picture of him doing his one handed typing. Blackmail is always fun, or you could just show it to you parents.
Step 6:
Buy your own computer so you don't have to let anybody else use it, it's always nice to let them use it though.
