text: would you tell on your friend with the std? if your friend had an std and your other friend wanted to fool around with her because the girl with the std said she was clean, would you tell the other friend that the girl had the std? or would you not say anything? my friend(we'll call her k) wanted to fool around with another friend (we'll call her j), but j has an std. j told k that she didn't have any std's, though... so when k asked me about it, i told her the truth... that k did have an std... was i wrong for doing that? i think you did the right thing, however you could also tell j that you were going to tell k that j has an std. it would be fair to give j an extra chance to tell the truth
