Don't cry. It's only a joke! Why do you always take everything so seriously always. I swear to God. You know, like, if you’re Dad made your joke you’d just laugh. But with me, it’s like the end of the world or something. Or you’ll look at me like I’m saying the stupidest thing you’ve ever heard. I’ve got news for you. Your jokes aren’t always funny either. Sometimes you make me feel like I’m wasting my time even trying.
