What I have found is that real friends stand by you.

Real friends are very special, but you have to be careful because sometimes you have a friend and you think they are made of rock, then suddenly you realise they're only made of sand.

Champagne for my real friends and real pain for my sham friends.

Tell people how it is, be real and be honest.
If you see something wrong make sure you speak up.
Being this way will naturally eliminate the snakes and fakes.

Friends are not a number. You can't collect connections. You can't just go out one day and be like, "Hey, I need some friends!" *goes shopping, scours social media*

A friend will fight for the truth, not distort it for their personal gain.
