The reason you have a spare is because you might need it in the future.
People seem to think that “spare” means that it’s useless, but it’s exactly the opposite. It’s “spare” because it’s useful to you. So it’s strange that people think you would give something away just because it’s “spare,” because that just means you’d have to acquire another spare for yourself.
Would you give away the spare tire for your car just because somebody asked you for it?
Fun fact; someone needing it is exactly why you have a spare, too. I would give my spare tire to a stranger that needs it, because that’s what a spare is. Then I get a new one. Edit: otherwise your spare is useless when you don’t need it.
Why don’t you have two spares in case you have two flat tires?!?
