when is a friend not a friend?

when you have no option about whether they can call you their friend

not that I don't want to be called helmut's friend, but it is the issue of whether someone else can determine this and the impact that this could have... if I do not agree with/like someone but they are happy to call me their friend - this may well say something about me that I would rather it didn't...

What got me thinking about this was I have been trying to take the reputation survey here

but it doesn't seem to be working :(
oh well - it is microsoft...
