How come paper cups can hold hot coffee for hours, but a paper straw turns to mush after 10 mins?

Just wondering about this as a I see a co-worker drinking multiple cups of coffee from same cup. And then whenever I get a drink while im out and then give me a paper straw, it becomes useless if I don’t finish the drink quickly.

The cup is wet only on one side, inside where it has thin plastic lining. The paper itself doesn’t get wet with the drink. The straw though, the paper definitely gets wet all over.
