Judi Sutherland: The Pessimist's Glass

See how this glass is half empty?
There's not much left in it at all.
I don't mean to be whiny,
but the measure looks tiny,
and the glass is, itself, rather small.

"The problem is quite elementary,"
quipped my friend, the astute engineer;
"the tank's oversized
for the process devised
for this miserable drop of small beer."

Everyone else has got plenty,
so I don't know quite what I should think.
I wouldn't complain,
but what this glass contains
is entirely the wrong sort of drink.
