Beauty Has No Duty

What is wrong with the following sentence?
(quote):  “There’s nothing wrong with this sentence.”

Those who remember their childhood
remember too much…
(and not very well at that.)

One chap said he found he could
“think much better” when using
a Greek name and archaic ideas.

You can come in during the middle of the play,
and it won’t matter. (Unless a human wrote it.)

Beauty has no duty…
(and that, says Uncle Faraway,
is the beauty of it,
and why all heroes are ugly).
