So last night, I went out with some friends and some of their friends. Long story short, someone drank from my drink/straw just before I did. They had no signs of cold sores whatsoever but not knowing anything about these people is terrifying. What is the probability that I'd get Herpes 1 from drinking from the same straw right after them? I know for a fact I'm negative for both so this has been beyond worrisome for me.
