You know those old ribald jokes that answer every question with the same phrase (e.g. "between the sheets", "that's what s/he said", "if you don't, somebody else will"... )?

Well, around here, the phrase that answers every question is, "Everyone's different."

So some of us began very nearly the same as you, some quite different, and anywhere in-between.

I guess another way to put it is, "PNs are like fingerprints/snowflakes—every one is different."
