Conceal thy thoughts ...

What one feels,
none will be aware -
if one does not, one one's face,
display one's wares ...
What one thinks,
none will ever get to know -
if one does not shelve one's thoughts,
neatly in a row ...
What one is capable of,
others won't even guess -
unless one is put
to the test!
What one does not write,
others will never know -
save if they are close,
and one's feelings do show ...
