This is actually not helpful.

Also, consider this:

 

Everything @Kurt-Dekker said is true.
However, as I was scrolling down, I did see at a glance a glaring issue.

Methods should always start with a capital letter. Get in this habit. Especially when they are one of Unity's magic methods.
start() should be Start()

 

This ^^^

Start() and start() are different method names. So the error you're getting is likely a null reference error inside the Rotate method because start() is never run to set "parent".
