[Double Happy]

Привет! В приведенном ниже текста песни Боба Дилана Heart of mine
не понятна только выделенная фраза.Может быть, кто-нибудь знает ее значение? Заранее благодарен.

Heart of mine be still,
You can play with fire
But you'll get the bill.
Don't let her know
Don't let her know that you love her.
Don't be a fool, don't be blind
Heart of mine.

Heart of mine go back home,
You got no reason to wander, no reason to roam.
Don't let her see
Don't let her see that you need her.
Don't put yourself over the line
Heart of mine.

Heart of mine go back where you been,
It'll only be trouble for you
If you let her in.
Don't let her hear
Don't let her hear where you're going.
Don't untie the ties that bind
Heart of mine.

Heart of mine so malicious and so full of guile,
Give you an inch and you'll take a mile.
Don't let yourself fall
Don't let yourself stumble.
If you can't do the time,
Don't do the crime
Heart of mine.

[atch-ramirez]

go over the line — перейти предел; перейти границы, выйти за границы дозволенного

[Irina Sergeevna]

Don't put yourself over the line -- не переступай ( я так думаю)

[RicardoRdR]

Русский вариант этой фразы: "не перегибай палку"
Хотя здесь можно перевести и как "не лезь в мое сердце"
