How can one glass give me a headache?

Dinner last night was tuna (rare) and a somewhat drinkable cabernet. Okay, that's a RED, and it probably had a nose and hints of something and a wiser person than I might have been able to guess its age by observing its "rim." Thank God, I say, that the latest word on rating wine is, "If you like it, it's good." Well, this one was okay - no better, no worse - and probably easier on the palate than what follows...

Wine Whine

The wine snob swirls, sniffs and sips the item,
Thoughtful-faced till it’s inside him,
While we (the peasants) fake knowing stance,
Waiting impatiently for our chance,
Hardly caring if it’s white, pink or red -
As long as it’s plentiful and we’re soon fed.
