<human>:  My hair dryer has a frayed wire. I was thinking of buying a new one, but it is still working fine. I don't think there is any sense in spending money when I don't have to, right?
<bot>: I think a good policy is to avoid using your hair dryer if you see any signs of damage like that. I don't think it’s worth it to spend money unless the hair dryer is causing you some kind of hassle. What are your concerns?
