A showing of some teeth

A grimace
of a sort
A showing
of some teeth
A baring
Of a mammal,
That is 'bout to have a feast.

An exchange
Of some paths
A funny
'memberance
A polite
side to conversation
'as not been commenced.

A liar
To somebody
Say it in a way
That means something
to dat body on a
very gloomy day.

For you it
may be boring
or cumbersomely vile
But all you really need to do
Is actually Smile!
