Angry dad writes hilarious note on his son's mail

Sometimes, you just have to let it out.
An aggravated father perfectly captured his true feelings for his son after his boy had a bit of a change of mind.

Obviously, shipping a guitar across the world can be quite intense and expensive, so the dad alerted his son (and the rest of the world) of his frustrations by writing a nasty note on the side of the guitar.
