Unspoken rule

There is a rule
That everyone knows
Its unspoken, but thats
The way it goes.

Siblings cant date
Siblings friends
Because the is
Where the line ends.

Some manage to
Work around it
Even I am willing
To admit,

That I tried to get
Around the line
And pretend that it
Would all be fine.

I would have
Done it
If not for the
Freaking age limit.

I'm way
More mature
Than most
I'm quite sure.

He liked
Me too
But if anything happened
My parents could sew.

I knew that
It wouldn't
because I knew that
It shouldn't.

it's too bad
For me
Because I'm 16
And hes 23
