Changing A Bike Tire

Is it wrong to assume I can run
over a spiky rock?
A tire worth its rubber
should be able to take
that much abuse,
I would think.

Is it weird to think
that I can hit a dirt patch?
Maybe take a little off-road
detour without my bike tire giving up
and passing wind with a slow
unforgiving wheeze?

Can it sense my whining?
My sighs of dismay?
Does it like the walk home,
rolling slowly down the street?

My guess is it does, because here I am,
on the side of the road, with a backpack full of groceries
like a billion times before.

"I guess you shouldn't of been so adventurous,"
I say to myself,
yet my tire will pop the same way every time.
