Take a pick: What should I listen to on my walk today? Linkin Park's "Living Things". Shinedown's "Amaryllis". Avenged Sevenfold's "Nightmare". Or Breaking Benjamin's "Dear Agony". The choice is yours. Choose wisely.
Neither is not an option. Never is it an option and I hate when people say it when given a choice. Obviously you're supposed to pick one, so freaking pick one.
... but the walk is only 40 minutes long at maximum. And I can't take super long walks otherwise my leg starts to hurt (sprained my knee from a car accident over 11 years ago).
