You said:

    "I'm 38. I date in my age group. Which means both of us are dating people that have been sleeping with others for two decades"

    > I did not sleep with other people while younger, why do you think it's OK to assume that about the parent commenter

I now realize was a quote from the poster above you, who must have edited it afterwards which is why it didn't show up when I searched for it, trying to follow the thread
