Alright I'm going to attempt to explain this without confusing you or 
myself.

Using '&' is basically comparing. It returns a value if not false.

1 & 2 #=> 0
2 & 2 #=> 2

Using '&&' is self evident.

"hey" && false
#=> false

"hey" && 10
#=> 10

true && false
#=> false

false && true
#=> false

Regards,

- Mac
