pg rating???????? But why?

I just wondered why a poem of mine got a PG rating.

I can't remember the title; it's in my Splintered Glimpses thing. Is it because the letter X was in the title? Is it automatic? Are the 'editors' real? Are any of us?

Does it mean Pretty Good? Cos I can't think of any other reason for it being PG-ed. Especially when my "Get Tae F**K Shakespeare" is a U.

Not that it matters in the slightest.

I just wondered, that's all.
