Brick Tunnel- by: unknown forgotten

I hate when I forget all the mysteries we love to ignore
And I sure hope I'm never stranded on an island because I'll grow wild
My endless bounds are held in premise
But I'm almost certain I can stand up to them all
Like magnets ripping boats apart
Or children growing way too old
How many ounces of oil can can the concrete absorb?
How far can the measuring tape reach before it folds?
Just enough to wash away
Just enough to reach farther than me
How much wind can wishes push aside?
I can build a structure stronger than it's insides
One with a cast iron door
