False friends will take advantage of you......
"False friends are like our shadow, keeping close to us while we walk in the sunshine, but leaving us the instant we cross into the shade."
- Christian Nestell Bovee
"Have you ever had friends who just couldn't be there for you when things turned dark? They want to hang out with you during the good times, but the minute things get hard they leave you behind. Often these types of people will wait until they think you're 'over' your hardship, and then call you up wanting to be friends again as if nothing had happened."
- Christian Nestell Bovee
"False friends are worse than bitter enemies."
- Scottish proverb
"An open enemy is better than a false friend"
