You boys have serious abandonment issues, you know that?
Fear of Abandonment & Loss: loosing their family
Nothing says “family” quite like the whole family being dead.
[ Sam and Dean lost their mother when they were children. Since then their father has been traveling around with them, often leaving his sons alone for days, even weeks. After finding Azazel John soon dies. The brother’s grandparents and all other known relatives got killed, too. Bobby Singer, who was like a father to them, gets killed by Dick Roman. Only Sam and Dean remain. ]
