As a result, they act surprised when it takes me 10 minutes to pick a sandwich or when I confess that I still get mild panic attacks when choosing floss at the drugstore.
结果当他们看到我花十分钟才点了个三明治，或者听说我在药店挑牙线的时候会小小地恐慌，都觉得不可思议。
If it's hard to manipulate the floss, use a floss holder or an interdental cleaner - such as a dental pick or stick designed to clean between the teeth.
用牙线清洁时，需要做到面面俱到。每清洁完一颗牙齿，都需重新截取一段干净的牙线。
