My password for uni stuff and eduroam is a random string. And by random I mean random. Half the reason I remember it is just muscle memory. My other passwords are random words in random languages.
I've got far too many friends who use their name or their home country or their mother's name as passwords and are just like "yeah, can't be bothered to type, my password is pakistan, just use it" and I just sit there and think "man, this person needs to learn not to trust me so much."
I make a point of not doing anything with their passwords because I know how much it can suck when someone has access to even the least used of your accounts, but man, it bothers me.
