How tall is the one whose glass is half-full;
how small is the one whose glass is a near-empty pool.
how sunny is the one who sees the bright side of things;
how gloomy is the one whose heart to clouds clings,
one smile, a snapshot of glee shared with a stranger;
one frown, a beast growling with anger.
a choice to be made:
for joy - will you be an open dooror barricade?

b) giving the ideas in a logical sequence creates a stronger
emphasis on the last stanza.
separating "frown" and "a" with a comma creates a stronger
visual image.
c) repeating the first words of each stanza creates a contrast thatreinforces the theme of unity.
d) setting off the last two words of the poem creates emphasis that reinforces the theme of choosing.
