what is time

Last night at rehearsal, the young (late 20s) woman sitting next to me was venting a bit in the break. Some friendship drama she's steeling herself to deal with, housemate may have hooked up with someone she wished he hadn't, not clear to me if she is jealous of the hookup or the housemate or both, not really my business, but anyway at one point I said "Wow—I have no real memory of being single," and I absolutely did not mean to trivialize anything she is going through!, and fortunately she didn't take it badly at all: She said "That is very good perspective, thanks for saying that."

(And I've only been married 11 years. I do have a fair few memories of being single? but there are a lot of past lives I can look back at now and realize things that were so important then don't really matter at all anymore now.)
