I'm a poet but not gay

I thought I might try and write something about my friends - the term poetry might be stretching it a little bit. These are more like limericks. Here's the first couple of attempts:

What a friend indeed is Caroline Mead!
About the Sis of Chris, I must insist:
She's the nicest person you could know,
so not dissimilar to her big Bro.

Does Olivia use Nivea?
Her face is less stressed than years ago,
and smiles now sit where frowns would go.
The furrowed brow has left the head,
was the product the cause
or has she just chilled out instead?
