as far as im aware u cant see other people's friend list apart from their vu homepage...though that will only show the first 8 people if they have alot of friends. sometimes people do hide their friend list on the homepage. the only way u can kinda guess is by seeing if they follow each other cuz when u add people vu will have u automatically follow that person though sometimes people will unfollow or random people will follow them back so that is like 50/50 chance.
