As the The Fresh Prince once said:

With the first encounter of love comes immense confusion. The person is never truly sure about their feelings, just know their thoughts revolve around their person of interest ie. she’s catching feelings.

She has yet to realize how crazy in love she’s become. This minute is either slang for “a little while” or an actual sixty seconds. She can’t live or be without him. She’s reached the level between obsession and infatuation.

Her jealousy has risen ten-fold to the point if he’s talking to any girl: friend, coworker, maybe family, she becomes angry because she wishes the attention to be on her.

Parker resides in Los Angeles, where Eric Garcetti is mayor, and he’s doing what LA residents do, smoking on that California weed.

“To make someone feel small” means one tries to belittle another to the point of embarrassment or disgraced to be in their own skin.

“The bigger one is, the harder they fall” is phrase pertaining to one’s success and losing it. It’s way harder for them to accept.

Birdy knows that it will be harder for him when he loses her than it will be her.

As Christina once said “words can’t bring me down”

The knife represents the words that said person uses against Birdy in order to break her heart.

I’m not bleeding is a metaphor. As one who was stabbed with a knife would bleed, Birdy understands that the words haven’t killed or damaged her physically. Therefore, she isn’t hurting.
