Three words Eight letters say it and im yours

Teenage years;
Your best friend becomes your enemy,
Your boyfriend becomes a dick,
Your closest friends bitch about you,
Lemonade becomes vodka,
Lollipops become cigarettes,
Undies become g-strings,
Bikes become cars,
Detention becomes suspension,
The only drug you knew was panadol,
The only thing that hurt you were skinned knees,
When protection meant wearing a helmet,
When parties meant party bags, hats and streamers,
When staying up late meant until 12 o’clock,
Goodbyes were only until tomorrow,
Remember when getting high meant swinging on the playground?
And we couldn’t wait to grow up?
