Life is a series of trial, error and occasional fuck ups. I don't have to tell you that much.
As far as what I've observed of you and Chase, you're both practically equivalent to that of two five year olds who bite and tease one another on the playground because their naive, childlike complexes and incompetency to effectively comprehend their feelings compels them to illustrate their adoration that way. But you know, the difference here is that they're five.
This is something you can at least try to manage not to fuck up, Penn. Just be honest about the way you feel and I can almost guarantee you that it'll make all of the difference in the world.
