It's only forever, not long at all.

Supermarket, oh what packet of crackers to pick?
They’re all the same, one brand, one name, but really they’re not.
Look, look, just choose something quick;
People are staring, time ticker-quicking
Skin is on fire; just choose something, something, something.
Pressure overwhelming
Next minute I am turning out of the door, facing one week without food.
A day, a day when things are pretty bad
But don’t let it make you feel sad,
the crackers were probably bad luck anyway.
