Whenever anyone I know asks to borrow my laptop if I'm not currently using it I log them on as a guest or if they are my friend or a potential friend I make them an account of their own. I find people usually consider having an account made for them a friendly gesture. I also tend to set the laptop on a flat solid surface for the borrower and I ask them not to move it. I am surprised how many unfriendly answers have been given to this question. :(

import antigravity is very cool but it's a darn shame that the print "Hello World!" example from the comic gives a syntax error. Sad.
