For every son or daughter that has felt abandoned...
#You are not alone!
Children that have experienced abandonment
Black is basically saying how through the pain that is brought after being abandoned, and how it effects them emotionally. This proves that it's a real problem, and it is not easily fixed.
This shows the message of how abandonment works with the mind of someone. Most people with parental abandonment go through this same cycle over and over again. It's not only because they fear the thought of someone leaving again, but the fear that they are not good enough.
This helps the campaign by showing the effects and the mindset of the people that have had this experience.
