Can I get herpes from sharing a drink?

Sorry if this is a stupid question. My sister has genital herpes. I’m not sure if she’s had an outbreak recently. Her partner also has it so is there a possibility she has it in her mouth? I accidentally took a drink of her coffee without thinking right after she did. Google says it can live for up to 10 seconds. Not sure if I should be worried now. We’re not super close so I’d feel awkward asking her if she has a current outbreak.
